Abstract
Изобретение относитс к горному делу и позвол ет снизить себестоимость добычи угл и повысить безопасность очистных работ за счет повышени устойчивости горных выработок (ГВ) и улучшени проветривани . Отработку столбов (С) ведут в восход щем пор дке. Выемочный С оконту- ривают вентил ционной I и конвейерной выработками . Очистной забой оборудуют механизированной крепью 3, угольным ком байном 4 и забойным конвейером 5. Определ ют зоны опорного давлени и расслоени пород кровли. Затем по мере подви- гани очистного забо угольным комбайном формируют новую ГВ 9. Вентил ционную выработку 1 при этом погашают. Новую ГВ 9 формируют в контурах границ смежного С вне зон расслоени пород кровли и бокового опорного давлени . Вслед за подвиганием очистного забо кровлю обрушают на секции крепи 10 сопр жени . За крепью сопр жени устанавливают органный р д стоек обрезной крепи 11 и посто нную крепь 12. Проветривание выработки осуществл ют с подсвежением исход щей из лавы струи воздуха. 3 ил. SS /The invention relates to mining and reduces the cost of coal production and improves the safety of cleaning operations by increasing the stability of mine workings (HB) and improving ventilation. The development of the pillars (C) is carried out in ascending order. Extraction C contour ventilation I and conveyor workings. The clearing face is equipped with a mechanized support 3, a coal mine 4 and a bottomhole conveyor 5. The zones of the supporting pressure and stratification of the roof rocks are determined. Then, as the coal miner moves up, a new HS 9 is formed. The ventilation output 1 is then extinguished. A new HW 9 is formed in the contours of the boundaries of adjacent C outside the zones of separation of the roof rocks and the lateral support pressure. Following the advancement of the clearing of the slab, the roof of the roof is brought down on the lining section of the 10 mates. An organ row of cutting struts 11 and a permanent support 12 are installed behind the support of the mate. Airing of the excavation is carried out with a jet of air emanating from the lava. 3 il.
