Panishko O. The substantiation of indices of frame-anchor support of the preparatory mine-workings under the conditions of coal mines of DHC "Shakhtiorskanthracite"

Three mine workings of pl. k2 and k3 of mine management office named after XVII party convention were determined as basic ones. As a result of processing the information obtained, the regularities of forming asymmetrical loading on a support of drifts were stated and its main parameters were determined.The simulation of mine workings with frame-roof bolting on a flat bench with the application of equivalent materials has been executed. It is established that mine workings with anchor support, in which the anchor is directed along the line of vector action of resulting external load in the point which corresponds to the angle of this force application, posses the greatest stability.The regularities and technical solutions obtained on their basis were implemented under the conditions of haulage gate of 12-th eastern drift of pl. k3 of hor. 460m of mine named after XVII party convention. The expected economic effect from the implementation of the activity will make up 7841000 hryvnas in Holding.
