PART VSHOTFIRING PROCEDURES

Duty to ensure safe shotfiring operations13

Every shotfirer and trainee shotfirer shall take all reasonable precautions to ensure that all stages of a shotfiring operation on which they are engaged are carried out in such a way as to ensure the safety of persons.

Stray electrical currents and voltages14

The manager shall–

a

take all reasonable steps to identify any risks to safety present during shotfiring operations which arise out of any stray electrical currents or voltages; and

b

(having identified such risks) set up a system of shotfiring which will minimise them.

Shotfiring fumes15

The manager shall–

a

take all reasonable steps to identify any risks to health or safety which arise out of toxic fumes produced by shotfiring operations; and

b

take effective measures either to eliminate those risks or (where it is not practicable to eliminate them) reduce them to the lowest extent reasonably practicable.

Priming cartridges16

1

A person shall not prime or assist with priming cartridges unless he is a shotfirer or trainee shotfirer.

2

A person shall not prime cartridges unless he is satisfied that–

a

all shotholes to be charged with the primed cartridges will be available for charging by the time that he has finished priming the cartridges; and

b

all the primed cartridges can be fired during his period of duty.

3

A person who primes a cartridge at the place where it is to be used shall place it in a shothole before priming any further cartridges.

Use of priming station and security of primed cartridges17

3

A person shall not–

Examination for general safety and tests for firedamp18

1

Immediately before–

a

charging a shothole or round of shotholes; or

b

firing a shot or round of shots,

the person who is to fire the shot or round of shots shall make suitable tests for the presence of firedamp and (where appropriate) an examination for general safety.

2

If any test carried out in accordance with paragraph (1) shows the presence of firedamp in a concentration of or greater than 1.25 per cent by volume or (where the estimated period of delay between the first and the last shot to be fired, calculated by reference to the markings on the detonators, exceeds 0.1 seconds) 0.8 per cent by volume, the person who made the test shall not proceed with charging or firing until the concentration of firedamp has been reduced below 1.25 per cent or, as the case may be, 0.8 per cent by volume; and when the concentration of firedamp cannot be so reduced, he shall–

a

inform the person having immediate control of the mining operations being carried on in the part of the mine where the relevant concentration was detected of that fact; and

b

take appropriate precautions to prevent danger arising from any shothole which he has charged but not fired.

Firedamp in the general body of the air19

1

Where any shotfirer or any person having immediate control of any mining operations being carried on in any part of the mine finds or has reported to him the presence of firedamp in a concentration of or greater than 1.25 per cent by volume in the general body of the air he shall take all reasonable steps to ensure that–

a

the charging of shotholes or firing of shots ceases immediately at–

i

the place where firedamp in the above concentration was found to be present, and

ii

any part of the return side of that place which is within the same district or part of a mine as that place;

b

the person for the time being in charge of the mine is informed forthwith; and

c

if the concentration of firedamp in the general body of the air cannot be reduced below 1.25 per cent by volume, appropriate precautions are taken to prevent danger arising from any shothole situated at the place referred to in subparagraph (a)(i) of this paragraph which has been charged but not fired.

2

Where the person for the time being in charge of the mine has the presence of firedamp reported to him in accordance with paragraph (1)(b) he shall take all reasonable steps to ensure that–

a

the charging of shotholes and the firing of shots are prohibited in any part of the mine ventilated by such air as has been found to contain firedamp in a concentration of or greater than 1.25 per cent by volume in its general body;

b

any charging of shotholes or firing of shots which has ceased in accordance with paragraph (1)(a) or which has been prohibited in accordance with subparagraph (a) of this paragraph is not resumed or, as the case may be, does not take place until he has–

i

satisfied himself that such resumption or taking place is safe, and

ii

authorised such resumption or taking place; and

c

the circumstances are reported to the manager.

3

The manager shall notify the Health and Safety Executive forthwith whenever the charging of shotholes or firing of shots ceases or is prohibited in accordance with this regulation.

he has allowed for suitable delay periods between the shots having regard to the circumstances of the particular case.

4

A person shall not charge a shothole or different shotholes in a round with primed cartridges which contain explosives or detonators of a different type from those used in the remainder of the charge or round concerned.

5

A person responsible for charging a shothole shall ensure that–

a

where necessary, the back of the shothole is plugged with stemming material;

b

the shothole is stemmed with a sufficient amount of suitable stemming material; and

c

any tool inserted into a charged shothole is made of wood or of an anti-static material.

he has satisfied himself that the person operating the winding apparatus is ready to raise the kibble.

Sentry’s duties24

A person who has been posted under regulation 23(1)(c)(i) to act as a sentry in respect of a particular danger zone–

a

shall forbid all persons (except the shotfirer whose duty it was to ensure that he was so posted or any trainee shotfirer working under that shotfirer’s close personal supervision) to enter that danger zone; and

b

shall not leave his post until the particular person who posted him to it has personally directed him to do so.

Duty to comply with sentry’s orders and notices25

A person shall not–

a

pass a sentry who has forbidden him to enter a danger zone in accordance with regulation 24(a); or

connected the detonator circuit to the shotfiring cable,

iii

withdrawn himself and any person with him from the danger zone, and

iv

tested the circuit for continuity and electrical resistance with an ohmmeter suitable for the purpose or the exploder testing circuit; or

(where transformer coupled electric detonators are to be used) he has–

i

checked that the primary looping wire has been threaded through all the toroids,

withdrawn himself and any person with him from the danger zone,

iv

checked the circuit for electrical impedance and tested the primary looping wire and the shotfiring cable for continuity with the exploder testing circuit; and

c

(in either case)–

i

he has determined that the electrical resistance or impedance of the circuit is such as to make a misfire unlikely, and

ii

it is safe to do so.

Operation of exploder28

A shotfirer or trainee shotfirer–

a

shall not place the removable handle or key in position in the exploder until he is about to use the exploder to test the circuit or fire a shot; and

Maximum number of shots29

1

The manager shall–

a

give each shotfirer written notice of the maximum number of shots he may fire or have fired during his period of duty; and

b
