矿井建设时期冲击地压防治程序与技术

Rock-burst Prevention Processes and Technology in Mine Construction Phrase

由于缺乏规范性程序指导,我国新建矿井建设期出现冲击地压难以应对的问题。以发生冲击地压的在建矿井为工程背景,分析了设计阶段、基建施工阶段冲击地压防治的程序与技术。结果表明,新建矿井应遵循冲击地压矿井识别、基于地应力的开拓巷道布置、采煤方法选择、煤柱宽度论证、合理煤层开采顺序等原则来指导初步设计;基本建设期间可针对冲击启动载荷源分源监测、分源防治,并形成采掘空间局部防治冲击地压的理论与技术体系。应用结果表明,理论与技术能够指导实践,已经在多个新建冲击地压矿井推广应用。

Aiming atscarcity of standard rock-burst prevention for new mines in construction phrase, this paper analyzed rock-burst prevention process and technology in design and capital construction phrase.New mines should obey following principles including rock-burst mine recognition, development roadway layout based on geo-stress state, coal mining method selection, coal pillar width design, and coalseam mining sequence selection, etc.In capital construction phrase, rock-burst start-up load monitoring and prevention could be applied to forming local rock-burst prevention theory and technology system.Application showed that this method could instruct prac-tice and had been used in several new mines with rock-burst.
