摘要
该文介绍了兖矿集团济宁三号煤矿综采放顶煤条件下上行开采沿空掘巷的锚网索支护技术,通过优化支护材料和支护参数,加大支护效果监测,满足了巷道掘进期间的安全、质量要求,延伸了锚网支护体系适用范围,对相似地质条件矿井有一定的借鉴作用。
This article describes the Bolt - mesh - anchor supporting technology of uplinking gob - side entry driving under the conditions of mechanized overhead caving coal mining about the Jining No. 3 Coal Mine of Yanzhou Mine Group, through optimizing supporting materials and supporting parameters, strengthening the monitoring supporting effect, satisfying the safety and quality requirements during the period of excavation of the channel, outspreading the use of Bolt - mesh - anchor supporting system, and there is a certain reference to the mine of similar geological conditions.
