摘要
以复杂地质条件下大倾角煤层开采应力场、位移场的分布规律及动态变化过程为研究基础,应用冒顶片帮处治成套技术,制定合理的大倾角煤层冒顶片帮控制技术方案,快速安全地处治综采面大冒顶片帮区。
Based on the distribution law and dynamic change process of stress field and displacement field of coal mining with steeply dipping seam under complicated geological conditions, at the same time ues the complete technique of roof caving and rib spalling treatment at the fully mechanized face with steeply dipping seam technique proposal of roof caving and rib spalling control in steeply inclined coal seams. The application of this technology, fast safe treatment of fully mechanized mining face roof fall help district.
