摘要
针对煤矿冲击地压类型复杂、治理技术缺乏针对性等问题,提出了以"分类治理"为核心思想的冲击地压"分类-评价-解危-预警-检验-支护-管理""七模块"治理技术体系。通过对矿井采深、地层条件、煤层条件、构造条件、开采方法和边界条件进行分析,提出了以8种不同的外部力源类型和10种典型巷道围岩结构形式两两组合的"深井冲击地压综合分类方法";在分类基础上对冲击地压的评价、解危、预警、检验、支护和管理技术进行了分析和优选。"七模块"冲击地压治理技术体系在山东能源集团新巨龙煤矿等矿井的成功应用,可为冲击地压矿井的安全开采提供借鉴。
Aiming at lacking dedicated control technique of complex rockbursts in coal mines,the authors propose a 7-component framework for controlling rockbursts based on rockburst classification,the 7-component framework includes classification,evaluation,danger-breaking,early-warning,inspection,support and management. Through analyzing mining depth,overburden,coal seam,tectonics,mining method and boundary conditions,the eight external load types and ten typical surrounding rock structures of under-ground openings are identified. Subsequently,a comprehensive rockburst classification scheme is presented using different combinations of external loads and surrounding rock structures.The evaluation,dan-ger-breaking,early-warning,inspection,support and management technology are analyzed and optimized based on rockburst classification. The 7-component rockburst control framework has been successfully applied in Xinjulong Coal Mine of Shandong Energy Group,and ensured the deep mining safety.
