摘要
为保证18201工作面跨空巷的安全,运用数值模拟手段分析了木跺支护参数的合理性,通过公式对回采期间工作面底板破坏深度及底板稳定性进行了计算分析,从理论上保证了工作面的安全回采。由矿压监测结果可知:工作面跨空巷回采期间,围岩没有出现塌陷、断裂等破坏情况,采取木跺支护是合理的。
To guarantee the safety mining of 18201 working face, numerical simulation is used to analyze the support parameters of wooden stamp support. Through the formula, the depth of coal seam floor damage and the floor stability of working face during mining period is calculated, which guarantees the safety mining of work face in theory. The mine pressure monitoring results show that the damage of surrounding rock does not appear and the support parameters of wooden stamp are reasonable in the caving mining face passing through the abandoned gateway.
