Изобретение относитс к горной промышленности и можег быть использовано при разработке крутых и наклонных угольных пластов дл охрань. подготовительных выработок.The invention relates to the mining industry and can be used in the development of steep and sloping coal seams for protection. preparatory workings.
. Известен способ охраны подготовительных выработок при разработке угольных пластов, включающий выклашсу бутовых полос вслед за проходом очистно го забо flj.. There is a known method of protecting preparatory workings in the development of coal seams, which includes the removal of rubble strips following the passage of the flj.
- Известен также способ охраны подготовительных выработок при разработке крутых и наклонных угольных пластов, включающий возведение искусственных целиков вслед за проходом очистного с использованием породы в качестве наполнител путем подачи св зующего материала и ускорител процесса твер цени в породу 2. - There is also a known method of protecting preparatory workings during the development of steep and inclined coal seams, including the erection of artificial pillars following the passage of a sewage treatment plant using rock as a filler by supplying bonding material and accelerator of the process of turning into rock 2.
Однако оба указанных способа характеризуютс значительной трудоёмкостью .However, both of these methods are very labor intensive.
Целью насто щего изобретени вл етс устранение указанного недостаткаThe purpose of the present invention is to eliminate this drawback.
Поставленна цель достигаетс тем, что св зующий материал и ускоритель процесса твердени нагнетают из выработки в обрушенные и перепущенные через перфорированные трубы, которые размешают в породах, и использованные трубы оставл ют в породах после нагн тани в качестве арМировки.This goal is achieved in that the binder material and the accelerator of the hardening process are injected from the mine into crushed and passed through perforated pipes, which are stirred in the rocks, and the used pipes are left in the rocks after compression as reinforcement.
Способ заключаетс в следующем. При The method is as follows. With
0 разработке крутых и наклонных угольных пластов вслед за проходом очистного забо в обрушенных и перепущенных породах около выработки размещают перфорированные трубы, через которые из выра5 ботки в указанные породы нагнетают св зующий материал и ускоритель процесса твердени . После нагнетани использованные трубы оставл ют в породах в качестве армировки.Following the development of steep and oblique coal seams, a perforated pipe is placed in the collapsed and retrained rock formations near the mine through which the bonding material and the accelerator of the hardening process are injected from these rocks. After injection, the used pipes are left in the rocks as reinforcement.

Данный способ позволит уменьпгить трудоемкость возведени искусственных целиков дл охраны выработок.This method will reduce the complexity of the construction of artificial pillars to protect the workings.
