Description

формула изобретейи  Способ управлени  основной кровлей при разработке пологих и наклонных угольных пластов, включающий бурение шпуров в почву пласта из очистного забо  и их взрывание , отличающийс  тем, что, с целью уменьшени  трудоемкости и повышени  эффективности процесса управлени  основной кровлей, бурение шпуров производ т группами с рассто нием между группами по линии, параллельной направлениюThe invention of the method of controlling the main roof in the development of flat and inclined coal seams, including drilling holes into the soil of the seam from the clearing hole and their blasting, characterized in that, in order to reduce the complexity of the main roof, drilling of bore-holes is done in groups distance between groups along a line parallel to the direction

отработки, равным 2/3 шага посадки основной кровли, а взрывание luiiypoa осуществл ют после обрушени  непосредственной кровли.working out equal to 2/3 of the landing step of the main roof, and luiiypoa blasting is carried out after the collapse of the immediate roof.
