摘要
为有效防治富水顶板特厚煤层出水压架事故,基于对崔木煤矿21303综放工作面现场观测、矿压数据及理论分析等,研究了见方来压与出水之间的联系,建立了覆岩结构破断与反复出水关系模型,并提出了以见方步距、支架阻力、长观孔水位、周期来压为核心的综合预警指标和针对性出水压架防治措施,对矿井安全生产具有实际的指导意义和借鉴作用。
In order to effectively prevent water-burst and support jammed disaster in mining extremely-thick coalseam under water-rich roof, based on field observation , underground pressure data and theoretical analysis , the relationship of weighting in square phrase and water-burst was researched and the model of surrounding rock breakage and repeated water -burst was set up.The comprehensive a-larm indices including square pace , support resistance , water-level of long-term observation well and periodical weighting and preven-tion measures were present , which would indicate and provide reference for safe mining of mine .
