Essay

Dissertation is devoted to problems of a support of a long roadway stability. The essence consists in finding and use of a space character of moving rock-blocks near to an roadway outline. The new direction in control of a rock behavior in a neighborhood roadway develops in this dissertation. It basis on limitation of space degrees of mobility of adjacent sites rock-blocks mass near to an roadway outline. The new principle of limitation of space mobility adjacent rock-blocks near to an outline with the help of special anchors orientation is offered. It is justified by outcomes of physical simulation and mining experiment. The way of a support of a long roadway stability in a dynamic zone of abutment pressure is developed with the help of space holding legs orientation. The ways which are offered are checked successfully in mines.
