## Instructions for Remainder of Workbook

The remainder of the workbook is presented in programmed instruction as described in the instructions to the program. This will help you learn faster - and remember the material longer.

## Introduction

Our intentions in this program are to help you establish an accurate, efficient system of record-keeping for drilling and blasting activities which will meet the requirements of the regulatory agencies and your Company. Now, we don't mean hard, fast rules - but rather, guidelines which can be adjusted to fit your particular situation. Your forms may vary somewhat from those shown here, the titles of the various positions may be different at your mine, and your operations may call for some variations of this system. The general guidelines, however, will apply. What we'll present here will be a workable system that will enable you to see how accurate record-keeping can be accomplished in a thorough, efficient manner.

In the film presentation, we talked about many of the things which were necessary for the opening of a new mine. If your mine has been in operation for some time, you probably have a system worked out for the basics we discussed. However, you may want to review your system to see if there are areas in which you can make improvements. And remember, in addition to Company policies and practices, you must be knowledgeable of the applicable regulations so that you can make certain you're satisfying all the requirements.

## Drilling and Blasting Preparation

**1.** Up to this point in our studies, we've discussed the logical steps to take for the opening of a new mine. The mine is to open shortly, and there are a few more steps which must be taken in preparation for drilling and blasting activity at your mine. We're going to talk about the paperwork you'll accomplish as the next step in the system. First, you'll need to complete the Drill Summary. There should be a separate Drill Summary for each drill on each shift.

**2.** As you'll recall, the Drill Operator's Report and the Daily Drill Report were discussed at the end of the film presentation as two of the three forms which are the basis for many of the reports which you must complete. The Drill Operator's Report should show the following information. (CHECK ANY CORRECT ANSWERS):

- A. hole numbers.
- B. depth of each hole.
- C. delay time lengths.

**3.** This report is usually completed by the (drill operator/shooter - which?) _____________ on (one shift per day/each shift - which?) _____________.

**4.** The Daily Drill Report, also discussed in the film. You'll also need the information from this form for your Drill Summary. As you'll recall, this form is kept (in your office/on the explosives truck - which?) _____________.

**5.** This report identifies how each hole was loaded by _____________ number.

**6.** The Daily Drill Report is filled out by the shooter, and a separate report (should/need not - which?) _____________ be completed for each shift.

**7.** So you should be able to complete your Drill Summary by using the information contained in the _____________ and _____________.

**8.** Let's move on now to the Daily Shooting Material Report, which you must complete and furnish to the warehouse for explosive charge-out purposes. The Daily Shooting Material Report is completed by simply totalling the explosive items and quantities listed on the Daily Drill Report. It is simply a summary of the _____________ items used during the day.

**9.** The next form to be completed is the Drill Down Time Report. This report is completed by totalling each delay in operation, as listed on the Drill Operator's Report, and entering these delays in the coded areas on the form. Like the Drill Summary, there should be a separate Down Time Report for each (shift/day - which?) _____________.

**10.** Logically, the Drill Efficiency Sheet provides a reference, on a daily basis, of each drill's performance. As these efficiency sheets are completed, the Division Drilling and Blasting Superintendent - or equivalent - should be provided with this information so that he/she will be informed as to the (CHECK THE CORRECT ANSWER):

- A. monthly drill performance.
- B. weekly drill performance.
- C. daily drill performance.

**11.** Another report is the Detonator and Delay Report, which is also completed daily. As suggested by the name, this is a means of keeping track of the usage of _____________, both electric and non-electric. All the information required to fill out this sheet can be found on the _____________ Report and the _____________ Report.

**12.** The next form is simply a log on which you record the times when blasts are detonated at your mine. This log provides a reference which will be helpful when you send in the seismograph tapes, since it is a record of the dates and times of _____________.

**13.** Finally - the Bit Report. This report is used to keep track of bit life on the drills and the cost per foot of drilling. A bit change on the drill should be indicated on the Drill Operator's Report. It would be a good idea for the drill foreman to record the serial number of the new bit, plus the number of the bit being removed if it's still legible. So the Bit Report is simply that - a report as to the life of the bit used.

## Report Matching Exercise

**14.** Match the name of the report to its best description by placing the number of the report beside the statement which explains its purpose.

### Reports:
1. Drill Summary
2. Daily Shooting Material Report
3. Drill Down Time Report
4. Drill Efficiency Sheet
5. Cap and Delay Report
6. Shooting Times Log
7. Bit Report

### Descriptions:
- _____ A. Record usage of both electric and non-electric blasting caps.
- _____ B. To provide a record of drill bit life and help calculate cost per foot of drilling.
- _____ C. Drill summary for each drill on each shift.
- _____ D. Records of dates and times of blasts.
- _____ E. List of explosive items and quantities.
- _____ F. Daily report of each drill's performance.
- _____ G. Total of individual delays in operation.

---

**15.** Up to this point, we've been discussing the steps necessary to prepare for the drilling and blasting activity at your mine. These steps have also served to familiarize you with some of the forms you'll be responsible for preparing. We're going to assume that all the preparation has been done, and drilling and blasting have been started as planned.

**16.** To put into practice those concepts which we've talked about up to this point, we're going to go through the activities of a normal day. Your first task will be to collect the field paperwork for the previous day. Therefore, you'll go out to the drill to collect the _____________ Report.

**17.** When you go out to the drill and determine that drilling was done on the night, day and afternoon shifts, you'll pick up (CHECK THE CORRECT ANSWER):

- A. one report which includes all the information for all the shifts.
- B. three reports - one for each shift.
- C. two reports - one night and one day.

**18.** Now you must collect the three Daily Drill Reports which are kept on the _____________ truck.

**19.** These reports tell you how the holes, drilled on each of the three shifts, were _____________.

**20.** Before you begin your reports, you need to see the Drill Foreman and collect the Shooting Report(s). Once you've collected the field paperwork, you're ready to compile your reports and update information.
