通过对大倾角中厚煤层走向长壁工作面回采时顶底板活动规律及安全管理的分析,不断探索大倾角中厚煤层走向长壁炮采工作面顶底板垮落和安全管理的特点。针对顶底板活动规律和工作面安全管理采取相应措施,为大倾角中厚煤层走向长壁炮采工作面的技术参数的选择、安全技术管理提供了实际经验,解决了大倾角中厚煤层走向长壁炮采工作面在回采过程中安全管理难题。
Based on the analysis of roof and floor movement rules and safety management of longwall coal mining face when working in steeply inclined medium thick coal seam, the characteristics of roof caving and safety management in longwall coal mining face with continuous excavation are explored. Taking corresponding measures to roof top floor and surface safety management, this paper provides practical experience for the selection of technical parameters and management of safety technology for the longwall coal mining face moving into the longwall, Wall artillery mining safety management problems in the process of mining.
