摘要
阐述了中国目前过断层的主要方法,并分析了其适应性。以15012工作面过F1断层为例,通过方案比对确定了跳采过断层方案,根据开采实际给出了跳采过F1断层的关键技术。该工作面过断层实践表明,合理选择过断层方法不仅可以促使工作面快速推进,保证回采作业的连续性,同时也有利于采场安全管理。
The main methods of crossing fault in China are described, and the adaptability of it is analyzed. With 15012 mining face crossing F1 fault as an example, the skip - mining scheme for crossing FI fault is determined based on the comparison of schemes, and key technology of skip mining for crossing F1 fault is proposed according to the actual mining. The practice of the face crossing fault shows that the reasonable choice of methods for crossing fault not only can promote the fast tunneling of mining face, ensure the continuity of extraction operations, but also is conducive to the safety management of the stope.
