Abstract
Использование: изобретение, может быть использовано в горнодобывающей промышленности при разработке антиклинальных складок мощных угольных пластов. Сущность изобретени : толщу угл под гиб- ким перекрытием в замковой части перед его выемкой подрезают вертикальными врубовыми щел ми, которые провод т между выемочными штреками, пройденными у кровли и почвы пласта в граничных зонах замковой части с крыль ми, а выемку угл ведут одновременно с верхних и нижних штреков, начина от врубовых щелей с опережением со стороны верхних штреков . 3 ил. Usage: invention, can be used in the mining industry in the development of anticlinal folds of powerful coal seams. The essence of the invention: the thickness of the coal under a flexible overlap in the castle part before its excavation is cut with vertical cutting slots, which are held between the excavation drifts, passed at the roof and soil of the formation in the boundary zones of the castle part with the wings, and the excavation is carried out simultaneously with upper and lower drifts, starting from the cutting slits ahead of the upper drifts. 3 ill.
Description
ЁYo
Изобретение относитс к горной про- мышленности и может быть использовано при разработке мощных угольных пластов, собранных в складки.The invention relates to the mining industry and can be used in the development of powerful coal seams, folded.
Целью изобретени вл етс повышение эффективности горных работ. The aim of the invention is to increase the efficiency of mining.
На фиг. 1 показана схема подготовки замка складки к выемке и зоны размыва; на фиг. 2 - схем а отработки замка складки; на фиг. 3 - разрез А-А на фиг. 1,In FIG. 1 shows a diagram of the preparation of the crease lock for the notch and the erosion zone; in FIG. 2 - schemes and working out the fold lock; in FIG. 3 is a section AA in FIG. 1,
Способ заключаетс в следующем; подготовка к выемке замка складки начинаетс . с проведени выемочных штреков 1, 2, 3, 4, 5, 6, 7, 8 у почвы и кровли замка складки. Между выемочными штреками 1, 3, 5 и 1,2, 4, 6 прорезаетс щель 9 и в этой щели 9 монтируетс гибкое перекрытие 10. Затем толщу угл под гибким перекрытием 10 в замковой части перед выемкой подрезают вертикальными врубочными щел -ми 11The method is as follows; preparation for the removal of the crease lock begins. excavation drifts 1, 2, 3, 4, 5, 6, 7, 8 near the soil and the roof of the castle folds. A slit 9 is cut between the recessed drifts 1, 3, 5 and 1,2, 4, 6 and a flexible floor 10 is mounted in this slot 9. Then, the thickness of the corner under the flexible floor 10 in the castle part is cut with vertical slotted slots 11 in front of the recess
