复杂地质条件下综放面缩面工序优化与实践

工作面常因断层等地质构造的影响,推进过程中需进行工作面缩面,拆除工作面部分支架及相关设备,以保证工作面正常回采.文章阐述了济宁三号煤矿53-下 07(北)综放工作面缩面准备,施工工序及方法的优化组织,优化工作面缩面的施工工艺,该技术缩短了工期,保证了工作面正常回采,提高了资源回收率.此次实践对工作面缩面工艺进行了一次探...

Under complicated geological conditions mechanized face shrinking process optimization and practice , Under complicated geological conditions mechanized face shrinking process optimization and practice

Working face often due to the impact of faults and other geological structures, promoting the process of surface mining in need of face contraction, removal of face parts and related support equipment to ensure the normal mining face.. In this paper, Jining NO.3 coal mine 53next07 (North) working face, reduced working face surface preparation, construction processes and methods of optimization organization, optimize the working face shrinking surface construction technology, short construction period to ensure that the face normal recovery, improved resource recovery, reduction of face to face an exploratory process, this practice may be similar for subsequent mechanized mining face shrinking surface mining method selection for reference experience., Working face often due to the impact of faults and other geological structures, promoting the process of surface mining in need of face contraction, removal of face parts and related support equipment to ensure the normal mining face..
