摘要
在煤矿工作面掘进过程中,冒顶对安全生产危险巨大,为此,需要对冒顶进行综合防治.首先分析了掘进工作面发生冒顶的原因,主要有靠近地质构造区域、空顶距过大、掘进速度过快和支护不合理等;然后分析了防治冒顶的技术,主要有加强地质探测、加强顶板支护、控制掘进速度和选择合适的掘进方式等.可以为煤矿的安全掘进提供一定的参考.
Abstract
In the process of mining face excavation,roof falling is a great danger to safety production,so it is necessary to carry out comprehensive prevention and control of roof falling.Firstly,the causes of roof falling in driving face were analyzed,including proximity to geological structure area,too large spacing of open roof,too fast driving speed and unreasonable support;then the prevention and control techniques of roof falling were analyzed,including strengthening geological detection,strengthening roof support,controlling driving speed and choosing suitable driving mode.It can provide some reference for the safety of coal mining.
