摘要
煤矿开采中断层易引发覆岩破坏,导致突水事故。为保证五沟煤矿区1031采区工作面安全绿色开采,运用FLAC3D数值模拟软件,模拟了复杂地质体完整情况和断层情况两种工矿在采动影响下对煤层顶底板变形的影响过程,模拟结果表明:覆岩应力应变、顶底板破坏深度随着工作面推进逐渐增大。本次分析结果为采动岩层突水性的防治提供了科学依据,有利于煤矿的绿色安全开采。
The fault in coal mining will be easily lead to overburden damage and water inrush accidents.In order to ensure the safe green mining of 1031 mining face in Wugou coal mine area,By FLAC3 Dnumerical simulation software,simulated the influence of complex geological body integrity and fault on the deformation of coal seam roof and floor under the influence of mining.The simulation results show that the stress and strain of overburden,the failure depth of roof and floor increase with the advance of working face.The result of this analysis provided scientific basis for the prevention and control of water inrush of mining strata,and is beneficial to the green and safe mining of coal mines.
