摘要
为了降低工作面煤尘,煤层注水为有效方法,根据长沟峪煤矿-140m水平4槽1工作面的地质特征,确定了煤层注水方式与注水参数以降低煤尘。建立了煤层长孔注水的渗流动态数学模型,利用多物理场耦合分析软件COMSOL,对不同工况下注水侵润半径进行了数值模拟,结果表明该煤层注水方案的可行性和有效性。
Water injection into coal is a good method for reducing dust in mining face. Based on geological characteristic of 4-1 Mining Face at -140m level in Changyugou Colliery, this paper researched water injection manner and parameters. It built up a seepage dynamic model of water injection in long holes by applying multi-physics coupling simulation software-COMSOL and numerically simulated infiltration radius of injecting water under different working conditions. Results showed that this design of water injection was feasible and effective.
