COAL MINES REGULATION ACTS. 1. In a mine ventilated by a furnace, with three separate ventilating districts and naked lights used

in each, inflammable gas is detected issuing from the face in one of the districts while the men are working ; state clearly what you would do (a) at the time, and (0) afterwards, were you in

charge. 2. Under what conditions may a seam of coal be worked by a singe shaft ? 3. Why is coal dust dangerous in a dry mine which is worked with safety lamps ? What special pre

cautions would you take when electricity is used for motors and lighting in such a mine? 4. In what circumstances is it necessary that only explosives on the permitted list be used under

ground?

Mention the precautions you would take before using them, in order to ensure safety. 5. What special precautions have to be taken in mines worked by safety lamps, when using electricity,

(1) for relighting lamps, (2) for firing shots ? Give reasons for the need of these precautions.

Two hours allowed for this paper.

MODES OF WORKING.

1. Describe fully the mode by which you would work the following coal seams lying at a depth of

200 fathoms, and dipping 1 in 21.
Show by a sketch plan and section how you would lay out a portion of the workings.

9' 0" Blaes (argillaceous shale), brittle.
0 8” Clod (carbonaceous shale), soft.
5' 5" Coal, very hard.
1' 10" Coal, very hard.

0" Hard fireclay.

all details and dimensions. 4. State how you would timber the working face and also the roadways of each seam given in Q. 1. 5. Great difficulty is experienced in keeping open the main roadways through the shaft pillars in a

seam 250 fathoms deep on account of the pressure combined with the weak inature of roof and floor. State in detail the plan you would propose for securing the roadways and the shaftbottom, giving your reasons.

Two hours allowed for this paper.

pumping engine supplied with steam from the same boilers, how would yon proceed ? -5. In addition to having a certificate, what are the qualifications necessary to fit a manager for an

extensive charge ?

One hour and a half allowed for this paper.

WINDING, HAULAGE, AND STRENGTH OF MATERIALS. 1. Make a drawing of a winding shaft suitable for an output of 120 tons an hour from a depth of

150 fathoms. Allow for ventilation and show all dimensions and divisions, specifying the kind

and size of guides and cages you would adopt with hutches to contain 10 cwts. each. 2. For such a shaft and output, and with steam at 80 lbs. per square inch, describe a suitable winding

engine ; giving sizes of cylinders, stroke, drum, sheaves, and ropes. State also the kind of foundation or engine seat you would provide, and the probable cost of the whole, including

engine house. 3. What are the qualifications requisite in an engineman for winding a large output from a deep

shaft ? 4. In fixing the site for a new colliery, what are the general conditions that should be taken into

account? 5. A pithead platform 30 feet by 12 feet is to be covered either with cast-iron or steel plates. State the

quantity and weight, and estimate the cost of each class ; specify the sizes and thickness you would use, and say which you would prefer for reasons given.

One hour allowed for this paper.

SURVEYING AND DRAWING.

1. Plot the following surface and underground surveys to a scale of one inch to a chain. Both

surveys begin at the centre of a shaft A. Surface Survey: A to B, N. 75o E., 103 links ; from B, along boundary, S. 2° W., 300 links. Underground Survey: A to C, N. 85° W., 55 links; C to D, S. 5° W., 210 links ; D to E, N. 87° E., 153 links; E to F. N. 84° E., 248 links; Fto G,

N. 5° W., 100 links ; G to H, N. 2° E., 111 links; H to A, S. 83° W., 323 links. 2. In Q. 1 give the area (in acres and decimals) of the seam worked beyond the surface boundary ;
