Ahead of the worked lava in the soil of the reservoir at an angle towards the lava through the side wall of the mine outside the lava support pressure zone, wells are drilled. By blasting charges B in the wells, a compensation gap is formed outside the zone of influence of the supporting pressure of the lava. Behind racks, lining workings from the developed space of lava form an unloaded area in the soil of the reservoir and install protective lining on this site behind the wall of the road up to the compensation gap.

Description
Изобретение относитс к горной промышленности и может быть использовано в подготовительных выработках, в непосредственной почве которых залегают весьма крепкие, но пучащие породы при бесцелико- вой разработке пологих и наклонных угольных пластов при расположении выработок на границе массив - выработанное пространство .The invention relates to the mining industry and can be used in preparatory workings, in the immediate soil of which there are very strong, but pulling rocks with purposeless mining of flat and inclined coal seams with the location of the workings at the boundary of the massif — the worked out space.
Цель изобретени - снижение трудоемкости бурени и взрывани скважин и ремонта подготовительной выработки.The purpose of the invention is to reduce the labor intensity of drilling and blasting wells and repair preparatory development.
На фиг. 1 изображена схема дл осуществлени способа; на фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - разрез Б-Б на фиг. 1.FIG. 1 is a diagram for carrying out the method; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.
Сущность способа заключаетс в частичной разгрузке пород почвы за счет образовани за стойками крепи выработки со стороны выработанного пространства лавыThe essence of the method is the partial unloading of soil rocks due to the formation of lining behind the support posts from the developed space of the lava.
разгруженной площадки в почве пласта и установку охранной крепи на этой площадке за стенкой выработки.unloaded site in the soil of the reservoir and the installation of security lining on this site behind the wall of the mine.
Способ осуществл етс следующим образом .The method is carried out as follows.
При отработке выемочного столба определ ют размеры зоны вли ни опорного давлени перед лавой. До этой зоны производ т из подготовительной выработки 1, оставл емой после прохода лавы дл повторного использовани , бурение скважин 2 и формируют компенсационную щельWhen mining the extraction column, the dimensions of the zone of influence of the reference pressure in front of the lava are determined. Prior to this zone, the preparatory mine 1, left after the passage of the lava for reuse, is produced, the wells 2 are drilled and a compensation gap is formed

Охрану подготовительной выработки дл ее повторного использовани осуществл ют следующим образом. Охранна крепьThe protection of the preparatory production for its reuse is carried out as follows. Security support

и устьем компенсационной щели 7 на разгруженной площадке почвы пласта.and the mouth of the compensation gap 7 on the unloaded platform of the soil layer.
Бурение скважин в почве пласта под углом в сторону лавы осуществл ют через боковую стенку выработки за пределами зоны опорного давлени лавы взрыванием за- р дов ВВ в скважинах образуют компенсационную щель вне зоны вли ни опорного давлени , а установку охранной крепи за стенкой выработки осуществл ют до компенсационной щели.Drilling wells in the soil of the reservoir at an angle to the side of the lava is carried out through the side wall of the excavation outside the lava support pressure zone by blasting explosive charges in the wells to form a compensation gap outside the zone of influence of the reference pressure compensation gap.
