Schedules and Drill Pattern Designs

Planning and Scheduling of overburden and coal drilling activities is one of the responsibilities of the Technical Services Department. The Drill and Blast Engineer uses geological models produced within a computer modelling package to establish drilling requirements within a particular pattern.

The ultimate aim of a drill schedule is to ensure that adequate; overburden is drilled and shot in front of the advancing dragline or face shovel / truck shovel and coal is drilled and shot in front of the truck/shovel operations.

Drill Operational Plan

Coal Drilling

The Drill pattern design will depend largely on the powder factor, expressed as kg/cm² and refers to the quantity of explosive product per volume of material to be blasted.  In determining the powder factor the Engineer will consider the following variables:

·         Geology

·         Depth of seam (drilling depth)

·         Design of shot

·         How coal will be extracted, ie: shovel, excavator, or front end loader.

Overburden Drilling

Pre-Split (if applicable)

Before the plan is completed a ‘pre-split’ line is marked out and drilled at approximately 4.5 metre spacings and to a pre-determined depth and angle.

A long section plan provides details for drilling of the pre-split. This plan includes information on the depth of drilling and the number of ‘marker’ seams to be drilled through before reaching the target depth/seam.

When the pre-split is drilled, geologists may conduct ‘wireline’ logging of these holes. This involves putting a probe down each hole, to determine the depth of coal or will use the info provided by the driller to determine depth of coal.

NOTICE !!!!!

When drilling along the pre-split line the drillers may drill every 5th hole down 2-3 metres into the main coal seam to assist with ‘wireline’ logging process.

Wireline’ logging may also be referred to as ‘borehole’ logging or ‘sirologging’.

As the plan is being completed the shotfirer will arrange for loading and firing of the holes along the pre-split line. After blasting the pre-split line, surveyors will place marker pegs along the pre-split, at 4-5 hole spacings. This pre-split line then becomes an important reference point for the completed drill plan and for marking out of the drill pattern.

Drill Plan and Pattern

The Drill Operational Plan (see illustration below) contains the following important information:

·    location of holes (relative to pre-split)	·         total metres to be drilled
·         depth of each hole	·         target metres per shift
·         spacing of holes	·         days of drilling required
·         drilling angle

The drill pattern for drilling generally follows basic guidelines,

·    Overburden drilling - the first hole is set at
       approx. 4m  from the presplit.

·   Coal drilling – the first hole is set at approx
      5m from the face.                       

                                                                                   

Example Only:

Communication of Plan

The Drill and Blast Engineer discusses the proposed plan with relevant people, before finalising the plan. Once finalised a copy of the final plan is distributed.

The plan is then communicate with the operators by:

·           Bench talks

·           Consultative process

·           Hard copy issued to the drill operator

Drill operators are required to familiarise themselves with the plans and to coordinate their activities towards achieving the outcomes contained within the plans. There may however be times when it is necessary to deviate from the plans, reasons for deviation may include:

·           environmental conditions – excessive dust, too wet, flooding

·           geological conditions - highwall or bench might be soft or unstable

·           other hazardous conditions - equipment breakdown, etc.

If a problem is anticipated or a hazardous situation evolves the drill operator(s) will take appropriate action to manage the situation, or apply contingencies until the plan can be reviewed. All drill operators are encouraged to make suggestions to address potential problems, or to otherwise improve the efficiency of the Plan.

1.2.1                      Shift Handover

Overview

The shift handover is a process where the departing operator exchanges important information with on-coming operator.

The shift handover is an important part of the day’s duties for the drill operators, both on-coming and departing.

Any important information regarding the previous shift, changes to the drill access route, and any hazards that may have been detected will be relayed to the on-coming operator.

The discussions usually include:

·         Defects

·         Changes to plan

·         Drilling conditions                                                

·         Maintenance requirements or activities

·         General information

·         Hazards

Handover Information

The handover information will usually be:

·         Contents of the OCE’s report (legal)

·         Defects Log book entries (legal)

·         Access roads and hazards

·         Changes to the planned work

·         Drilling conditions

·         Tags

·         Maintenance

·         Planned moves

·         General reports and correspondence

Planned Moves

Information related to the status of the planned moves is passed on to the on-coming operator, eg: details from Drill Operational Plans.

Type of Drilling

Information relating to drilling or working conditions is discussed with the on-coming operator, including:

·         Drill Pattern

·         Angle and Depth of Drilling

·         Material to be Drilled

Ground Preparation

Requirements for drill relocation need to be discussed, including particular details of ground preparation required to ensure the drill operations can advance without delay.

Communication

Any important information shall be verbally communicated by your supervisor or if in the form of written reports or notices.  All written reports or notices shall be communicated individually to each operator via a hard copy or memo.

These reports or notices may refer to:

·         Maintenance issues

·         Operational issues

·         Supplier’s bulletins or updates

Tags

Tags are designed to protect personnel and/or equipment. The departing operator must inform the on-coming operator where tags have been placed, by whom, and for what reason.  

Daily Pre-start Defect Report

Each drill has one or more books for the purpose of recording pre-start  and defect information. The books are used to record:

·         Critical Defects

·         Operational Defects

·         Condition Defects

·         And action taken

Operators have a responsibility to ensure these forms are filled out every shift for each item of machinery operated, where required.

Daily Drilling Log

Each drill has one or more books for the purpose of recording Daily Drilling Log information.  The books are used to record:

·           Shift details

·           Metres drilled per hole

·           Production Hours

·           Delays/Downtime

The book is kept in the Drill Operator’s Cab; reports are completed by the Driller on shift.

Operators have a responsibility to ensure these forms are filled out.

1.2          Prepare for Work

The Trainer will Explain and Demonstrate the following procedures.

<><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><>><><><><><><><><><><><><><>

1.2.1                      Pre-Start Inspections

Operators are required to conduct an inspection of the drill and their immediate work area at each shift change and prior to starting the drill after periods of shut down.

At the start of the shift the on-coming operator may be required to complete drilling a hole prior to walking onto the location of the next hole and shutting down the drill before conducting the inspection.

The pre-start inspection at the commencement of each shift is a comprehensive ‘walk-around’ inspection of both the drill rig and the work area. All shifts are required to conduct this inspection if no ‘hot seat’ changeover has occurred, eg: after maintenance work.

Full details of pre-start and walk-around inspections of the drill are provided in Unit 3 – Start Up, Park Up and Shut Down.

1.2.2                      Marking Out Of Shot

Marking out of the shot for the control row echelon is the responsibility of the mine surveyor.  You may be required to infill between the burden and spacing.

Marking Drill Pattern:

1.      Referring to the Drill Operational Plan, the mine surveyor places markers (eg. Painted pegs or flagging tape) at the location of each hole.  Each marker is off-set to the hole so that the driller may sight and align the drill with the marker, thereby ensuring the hole is drilled in the correct location.

                                                                                                                                           

 

 

1.2.3                      Drill Access & Boarding

Drill Work Area Access

It is important to know that there is a drill access procedure and it must be followed for safety reasons. Access means getting into the area where the drill is working – not getting onto the drill.

Procedure:

1.        Call the Drill Operator on the two-way before entering the machine working area.

2.        When answering your call and request to board the machine, the operator will clearly state where to park your vehicle.

3.        You must not enter the work area until the drill operator responds to your call.

4.        Proceed with caution to the designated parking area, maintaining a safe distance from working equipment, eg: drill, dozer, water trucks, graders, service vehicles etc.

5.        Approach the drill cautiously and follow Drill Boarding Procedure to board the machine.

Boarding Drill

If personnel access is required onto the drill whilst it is in operation, the following procedure MUST be followed.

Procedure:

1.          Approach the drill from the right hand side (operator’s cab side), which allows the drill operator visual contact.

2.          Lower the boarding ramp / stairs by turning the control switch clockwise. Advance up the ramp / stairs to the operator’s cab. The operator will raise the ramp / stairs (if required) from the operator’s controls.

Stand Clear of the ramp/stairs as it is
