Visual inspection of <br />surface areas (without traverse surveys) above the mini working show no in- <br />dications of tension fractures, joints, or fault escarpments. However, the <br />surface may subside cniformally above a mined-out area without noticeable <br />visual effects that can only be determined by a precision survey of the sur- <br />face. Subsidence may be of the order on Holy fractions of an inch. Maximum <br />surtace subsidence ca:,r„t e:<ceed the thicknes.; of the coal removed. <br />The non-e:;is tense of visual distu rhances above the A1ue Flame Coal <br />Mine could indicate no ground subsidence due to coal extractions has reached <br />the surface. <br />6e advised that the Mine Plan Nkip accurate]y portrays mine development <br />and reflects the current status of the underground workings. The mining equipment <br />to be usod include the following: The standard type coal cutting machine, a joy <br />loading machine, both of whidi a.re electrically power^_d. After cutting the seam, <br />• the coal '.gill be drillad and blasted. T!ze rna]. will then be loaded via the joY <br />loader onto a 2 1/2 ton chattle car which will transport the coal to the mine sur- <br />face. C>t~ce on the surface, the coal will be off-loaded onto a shaker conveyor <br />~,-Kish in turn separates the coal in relation to its size.
