Description
Изобретение относитс к горной промышленности и может быть использовано при разработке полезцых ископаемых в услови х повышенного горного давлени , преимушественно на угольных месторождени х .The invention relates to the mining industry and can be used in the development of mineral resources under conditions of increased mining pressure, mainly in coal deposits.
Цель изобретени - повышение эффективности разработки путем повышени устойчивости выработок и предотвраш,ени динамических влений при бесцеликовой отработке пластов.The purpose of the invention is to increase the development efficiency by increasing the stability of the workings and to prevent dynamic effects during the purposeless mining of formations.
Способ осуществл етс следующим образом .The method is carried out as follows.
Впереди опережающей лавы .провод т подготовительную выработку. Из выработки бур т разгрузочные короткие скважины в сторону опережающей лавы и удлиненные на ширину выработки скважины вAhead of the advanced lava, the preparatory development is conducted. From the development of the drill t short discharge wells in the direction of advanced lava and elongated by the width of the production wells in
сторону отстаюшей лавы. Выработку погашают за очистным забоем лавы. За забоем опережающей лавы на заданном рассто нии от нее вдоль границы с выработанным пространством по массиву полезного ископаемого, разгруженного скважинами , длина которых увеличена на ширину или более выработки, провод т присечную выработку. Данную выработку располагают таким образом, чтобы рассто ние от забо side lagging behind. Production repay for clearing the bottom of the lava. For the slaughter of advanced lava at a predetermined distance from it along the border with the developed space in an array of minerals, unloaded by wells, the length of which is increased by a width or more of output, they perform secondary cutting. This production is positioned so that the distance from the bottom
скважин до нее было не менее ширины этой выработки. Между присечной выработкой и погашаемой дл изол ции выработанного пространства и улучшени состо ни выработки оставл ют полосу угл шириной не более 4 м. После проходаwells before it was not less than the width of this development. Between the secondary production and redeemable to isolate the open space and improve the state of production, leave a strip of coal with a width of not more than 4 m. After passing
отстающей лавы присечную выработку как правило погашают.lagging lava secondary production is usually repaid.
