Description
Изобретение относится к горной промышленности и предназначенно для охраны подготовительных выработок.The invention relates to the mining industry and is intended for the protection of preparatory workings.
Целью изобретения является снижение трудоемкости работ по охране подготовительных выработок при разработке угольных пластов.The aim of the invention is to reduce the complexity of the work on the protection of preparatory workings in the development of coal seams.
Способ осуществляется Следующим образом. ,The method is as follows. ,
При разработке пластов полезных ископаемых для охраны подготовительных выработок первично отработанного столба, используемых в качестве вентиляционных при отработке последующего столба, вдоль охраняемой выработки по мере подвигания очистного забод размещают ряд поддерживающей крепи по всей длине зон переднего опорного давления,During the development of mineral formations for the protection of preparatory workings of the primary spent column used as a vent when working out the next column, along the protected outlet, as the sweeping hole moves, a number of supporting supports are placed along the entire length of the front support pressure zones,
5 разгрузки, заднего опорного давления, а так же зоны статического давления впереди очистного забоя и зоны установившегося давления позади забоя.5 unloading, rear pressure reference, as well as static pressure zones ahead of the cleaning face and steady-state pressure zone behind the bottom.
Ю В каждой из зон крепь в рядуYu In each of the zones lining in the row
последовательно переносят в направле нии перемещения зон.sequentially transferred in the direction of movement of the zones.
Вне зоны опорного давления участками присекают бок выработки и бурятOutside the reference pressure zone, the sections of the side of the excavation and the drill are cut.
15 в кровле шпуры, которые заряжают и взрывают в зоне разгрузки.15 in the roof of the hole, which charge and blow up in the discharge zone.
