衰老矿井短壁条带绿色充填开采技术研究与应用
Research and Application of Short Wall Strip Green Filling Mining Technology in Aging Mine
摘要:
针对东坪煤业“三下”压煤量大、矿井资源衰竭、村庄搬迁困难等问题，必须探索新型的采矿工艺实现矿井现有煤炭资源的可持续开采，通过理论分析、室内试验和现场实测等手段，提出了短壁条带绿色充填开采技术，对工作面布置、充填材料配比、支巷参数和地表变形规律进行了研究，该方法已在东坪煤业15号煤层进行了实验开采，获得了较大的经济和环境效益，可为类似条件的煤层开采提供一定的借鉴。
Abstract:
In view of the problems of “three lower” coal pressure in Dongping Coal Industry and the difficulty in moving villages and the exhaustion of mine resources, it is necessary to explore new mining tech-niques to realize the sustainable mining of existing coal resources. By means of theoretical analysis, laboratory test and field measurement, the paper puts forward the continuous green filling mining technology. The working face layout, filling material ratio, branch and lane parameters and surface deformation law were studied. This method has been used in the experimental mining of No. 15 coal seam of Dongping Coal Industry, and has obtained great economic and environmental benefits.
