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.
