摘要
为有效控制工作面沿空留巷底鼓严重的问题,本文以店坪煤矿10-202工作面为例,对影响沿空留巷底鼓的5个主要因素进行简要分析,并对其底鼓机理进行研究,然后利用理论计算,得到10-202工作面沿空留巷的底鼓量为1479.7mm,最后提出相应的控制措施,在实际生产中取得了良好效果,有力保障了工作面的安全生产。
In order to effectively control the serious problem of the floor heave in the gob-side entry retaining, this paper takes the 10-202 working face of the Dianping Coal Mine as an example, analyzed the five main factors and the mechanism of floor heave, and then use the theoretical calculation, the amount of 7604 working face floor heave of gob-side entry retaining is 1082.7 mm, finally put forward the corresponding control measures and achieved good effect in actual production, guarantee the safe production of working face.
