摘要
通过对冀中能源股份公司邢台矿7712工作面内落差累计为2号煤全煤厚的断层进行分析研究,采取优化设计的措施。为保证工作面安全开采,避免逐渐缩减支架带来的拆除和运输不安全因素,提高煤质,通过合理优化设计补风巷,使工作面甩掉断层;在采线到达断层位置后,利用集中减架技术缩短工作面,实现了安全开采,在类似条件下的矿井有推广应用价值。
The fall accumulated as No.2 coal fault in 7712 working face of Xingtai mine was analyzed and researched,measures of optimization design was carried out. In order to ensure safe mining in working face, avoid unsafe factors to demolition and transportation, as well as improve coal quality, air supplement roadway was designed optionally to make working face get rid of fault. After mining line reaching the fault position, centralized reduction technology was applied to shorten working face, which realized safety mining and provided reference for coal mines with similar conditions.
