浅埋煤层房采采空区隐患分析与治理技术

    Goafs Hazard Analysis and Control Technology of Room Mining in Shallow Coal Seam

    • 摘要: 在现场调研与踏勘、勘查与治理方案编制工作的基础上,分析了浅埋煤层房采采空区主要存在资源安全隐患、井下安全生产隐患、地表建(构)筑物安全隐患、生态和社会安全隐患等4大类安全隐患,研究了浅埋房采采空区露天剥离治理技术、采空区注浆治理技术、未塌陷采空区顶板崩落治理技术、采空区残留煤柱充填回收技术等4种治理技术的优缺点和适用条件。

       

      Abstract: Based on the field investigation and reconnaissance, prospecting and control scheme compilation, four categories goafs hidden dangers of room mining in shallow coal seam were analyzed, that is, resources safety hidden dangers, mine safety production hazards, surface buildings and structures hazards, ecological and social safety hazards. Merits and demerits, applicable condition of four control technologies for goafs of room mining in shallow coal seam were researched including open stripe, grouting, roof collapse for non-collapse goafs and residual pillar filling for recovery.
