(54) СПОСОБ ОХРАНЫ ПОДГОТОВИТЕЛЬНЫХ ГОРНЫХ ВЫРАБОТОК(54) METHOD FOR PROTECTING PREPARATORY MINING WORKS
1one
Изобретение относитс к горному делу, а именно к охране подготовительных выработок угольных шахт и может быть использовано при поддержании пластовых выработок в услови х высокого горного давлени .The invention relates to mining, in particular to the protection of preparatory workings of coal mines and can be used to maintain reservoir workings under conditions of high mining pressure.
Известен способ охраны пластовых подготовительных выработок, основанный на повышении несуш,ей способности краевой части массива угл , прилегаюшей к выработке , сушность которого заключаетс в том, что упрочнение пласта производ т цементными растворами или синтетическими смолами 1.The known method of protecting reservoir preparatory workings, based on increasing the hedges, is the ability of the marginal part of the coal mass adjacent to the mine, the drying of which lies in the fact that the formation is hardened with cement mortars or synthetic resins 1.
Недостаток его заключаетс в том, что в услови х большого опорного давлени на больших глубинах разработки угольных пластов вл ютс недостаточно надежными, так как несмотр на упрочнение краевой части массива угл , она не выдерживает горного давлени и, деформиру сь, создает крайне неблагопри тные услови дл поддержани выработки.Its disadvantage lies in the fact that under the conditions of a large bearing pressure at great depths, the coal seams are not reliable enough, because, despite the hardening of the edge part of the coal mass, it does not withstand rock pressure and, deformed, creates extremely unfavorable conditions maintain production.
Известен также способ охраны подготовительных горных выработок, включающий бурение по пласту разгрузочных скважин большого диаметра 2.There is also known a method for the protection of preparatory mine workings, which includes drilling a large-diameter discharge wells 2.
Недостатком данного способа вл етс его невысока надежность в устойчивости краевой части массива, поскольку после использовани резерва податливости пласта, т. е. после того как пустоты, образованные скважинами, будут ликвидированы, происходит усиленна деформаци пласта в сторону выработки, и как следствие, разрушение ее крепи.The disadvantage of this method is its low reliability in the stability of the edge part of the array, because after using the reservoir compliance reserve, i.e., after the voids formed by the wells are eliminated, the formation is deformed in the direction of production, and as a result, its destruction lining.
1Дель изобретени - повышение устойчивости подготовительных горных выработок1 of the invention - improving the sustainability of preparatory mine workings
Поставленна цель достигаетс тем, что в скважинах размещают отрезки леса, которые соедин ют между собой металлическими скобами.This goal is achieved by placing wood sections in the wells, which are interconnected with metal clips.
На чертеже изображена горна выработка и прилегающий массив, поперечный разрез.The drawing shows the hearth production and adjacent array, cross-section.
Способ осуществл етс следующим образом .The method is carried out as follows.
