Description

(54) СПОСОБ ПРОХОДКИ ВЫРАБОТКИ В ОБРУШЕННЫХ И УПЛОТНЕННЫХ ПОРОДАХ(54) METHOD OF PASSAGE FOR PRODUCTION IN HEATED AND SEALED BREEDS

боткИ. Дл  экономии в жущего вещества его можно распредел ть так, чтобы образоаавались две полосы шириной, равной ширине проектируемой выработки и с таким же рассто нием между ними.botkI. To save in the substance, it can be distributed in such a way that two bands are formed with a width equal to the width of the projected output and with the same distance between them.

Дл  того, чтобы в жущее вещество не растекалось на большое простран .-ство, чем это необходимо, можно добавл ть наполнитель (например древесные опилки, стекловату), или примен ть смолы с естественной густой консистенцией. По мере оседани  вышележащих пород обрушенна  породам непосредственной кровли будет раздавливатьс  и дробитьс , а в обра.-, зующиес  пустоты будет проникать в жущее вещество, обволакива  частицы породы. Как известно, основное уплотнение обрушенных пород наступает спут  примерно 3-4 мес ца после.ведени  очистных работ в услови х лавыобычной длины.In order to prevent the spreading substance from spreading into a large space than is necessary, you can add filler (for example sawdust, glass wool), or use resins with a natural thick consistency. As the overlying rocks subside, the collapsed rocks of the immediate roof will be crushed and crushed, and the surrounding voids will penetrate into the burning substance, enveloping the particles of the rock. As it is known, the main compaction of the collapsed rocks comes about 3–4 months after the introduction of cleaning operations under conditions of normal length.

Поэтому схватывание в жущего вещества должно происходить не раньше этого срока и не позднее момента про ведени  выработки в подготовленном месте.Therefore, the setting in the substance should occur no earlier than this time and no later than the moment of keeping the production in the prepared place.

Выработка проводитс  через 3-4 мес ца между упрочненными полосами породы .The development is carried out in 3-4 months between reinforced rock bands.
