大采高综采工作面快速过断层生产技术实践

Practice on the production technology of rapidly passing fault for fully mechanized mining face with large mining height

基于哈拉沟煤矿22526综采工作面过F54断层生产实践,以割岩量最小化为原则,给出了过断层期间顶底动态割岩厚度计算方法和顶底割岩过渡段支架数量的计算公式,制定出过断层的生产工艺。实践说明采用上盘割顶、下盘割底对等割岩方式可作为综采面快速过断层的一种实用技术。

Based on the production practice of No. 22526 fully mechanized mining face through F54 fault in Halagou coal mine,taking the minimization of rock cutting as the principle,the calculation method of dynamic rock cutting thickness and calculation formula of the number of supports in the rock cutting transition section during the period of passing through fault was proposed and the production process of passing through fault was developed. The practice shows that the equivalent rock cutting way of cutting roof in hanging wall and cutting floor in footwall is a practical technology of fully mechanized mining face through fault.
