Method for preventing and treating rock burst by using filling mode

Abstract

The invention discloses a method for preventing and treating rock burst by using a filling mode and belongs to the technical field of coal mine safety production. The method includes the steps that a coal cutter cuts coal and feeds, a scraper conveyer conveys the coal, and a filling rock burst prevention hydraulic support protects side walls and supports roof; after a work face is advanced for a proper distance, a filling rock burst prevention material is adopted to implement filling and rock burst prevention on a goaf through the filling rock burst prevention hydraulic support; with the continuous advance of the filling operation, the filling rock burst prevention material is accumulated and compacted continuously to form a rock burst prevention body; the front stoping of the filling rock burst prevention hydraulic support and the rear filling of the filling rock burst prevention hydraulic support are conducted synchronously; after the filling operation meets requirements, a cycle of the work face filling coal mining is completed; the scraper conveyer is pushed to move to conduct a next cycle. The method for preventing and treating the rock burst by using the filling mode has the advantages that the active supporting capacity is strong, the integrality is strong, the setting lead is rapidly provided, crush resistance is achieved, tension resistance is achieved, the durable effect is achieved, yielding is achieved, water prevention is achieved, fire prevention is achieved, energy absorption is achieved, the low price is achieved, operation is convenient, the filling operation is rapid, the number of using personnel are less, the filling operation is simple, the road maintenance amount can be reduced, and the expense expenditure is reduced.

Description

technical field [0001] The invention belongs to the technical field of coal mine safety production, and relates to a method for preventing and controlling rock burst in coal mines, in particular to a method for preventing and controlling rock burst by using a filling method. Background technique [0002] Rock burst is a major disaster that threatens the safe production of mining industry. With the gradual development of coal mine resource mining in my country, the frequency of rock bursts is increasing, and its hazards are also increasing; it causes roadway surrounding rock damage, collapse and casualties, which has caused great harm to coal mine safety production. harm. Once a rock burst occurs underground, it will cause deformation of the roadway, roof collapse, bottom heaving, destruction of supports, blockage of the roadway, and even the closure of the roof and floor, thus affecting ventilation or overturning the equipment, causing production interruption, and may cause ...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the traditional filling coal mining method is to solve the coal seam mining problem of "three downs and ups" (under the water body, under the railway, under the building, and above the confined water body), slow down the subsidence of the surface, protect the mining of groundwater, prevent the gangue from going up the well, and eliminate Coal spontaneous combustion and other aspects of design services, but never applied in the prevention and treatment of rock burst
