摘要
以彬长矿区某矿40112工作面为依托,基于底鼓成因,制定"强帮强顶、底板卸压、底角加固"复合支护方案,并采用FLAC数值模拟对方案进行评价,结果表明底鼓量较少,为原来的33%,较好地控制了底鼓,满足安全生产要求,方案合理可行,可为类似工程提供参考。
Depended on the 40112 working face in Binchang coal mine, Based on the floor heave causes,proposed a compound supporting program that emphasized the strong slope and roof; release the press of ledger floor and base angle strength,with the FLAC numerical simulation, the result of program evaluation showed that the floor heave value was decreased 33% and its function was better, which was prove reasonable and effective and could regarded as a kind of reference to similar gengineer.
