摘要
针对充填体自立问题,介绍了不同开采条件下充填体的计算模型,进行了力学分析与比较,在此基础上建立了煤矿充填体的自立模型并进行了力学推导,研究结果对充填料浆的自立强度设计具有一定的指导意义。
In view of the strength of cement filling body, some calculation models of different mining conditions are introduced and analyzed in the paper. Furthermore, a new calculation model suitable to coal filling body is established and its force is deduced. The research has useful guidance for the strength design of filling slurry.
