Essay

Object: processes of working out parameters squeezing out rocks of floor in extracted areas of longwall retreating systems. bstantiation of mechanical resistance to rocks of floor of mine workings with a reverse working of a longwall. Purpose: substantiation of parameters mechanical resistance rock of floor for saving of their stability in working areas. Methods of researches: physical methods of design, analytical researches, visual and instrumental supervisions of ground pressure in underground conditions, using mathematical statistics methods. The possibility of rock resistance saving of the working after balance state distraction was first theoretically grounded and experimentally confirmed. Quantitative dependences of mechanical rocks rebuff for its resistance saving on the basic influential factors were received for the first time. It was set up that the necessary value of mechanical rock rebuff in 2-3 times less than the forces which work along the blasted rock zone perimeter and it is 1-2 timesless than the working support. Some recommendations on the developed method were accepted at "Yuzhnodonbasskaya" №3 mine and "Lydyevka" mine (State enterprise "DUEK"). The sphere of use includes coalmining enterprises, scientific researches, educational process.
