摘要
针对近距离煤层采空区下工作面前方存在空巷问题,对空巷围岩性质及物理力学参数进行分析,并建立了空巷围岩结构力学模型,通过采取超前空巷切顶及对空巷加强支护措施,可有效控制空巷围岩稳定,使工作面安全通过空巷。
Aiming at the goaf of close distance coal seams under the front of existing roadway, the roadway properties and physical mechanical parameters were analyzed, and the establishment of the structure of rock roadway model, through the adoption of advanced roadway roof cutting and strengthening of roadway supporting measures can effectively control the stability of surrounding rock roadway air, make work safety through abandoned.
