摘要
基于漳村煤矿2301工作面回采期间出现端面空顶面积大、顶板破碎严重现象,分析了工作面端面破碎主要原因,根据实际生产情况,提出注浆、锚索吊棚、管棚超前支护等联合支护措施,有效阻止了端面破碎现象,保证了工作面安全快速回采。
In view of the large empty roof area and serious roof breakage of the end face in the 2301 working face of Zhangcun Coal Mine,the main reasons for the end face breakage are analyzed.According to the actual production situation,combined supporting measures such as grouting,hanging shed with anchor cables and advanced support of pipe shed are put forward,which effectively prevents the end face breakage and ensures the safe and rapid mining of the working face.
