摘 要:为防止大倾角煤层综采工作面支架倒架发生顶板事故,研究分析了新疆焦煤集团2130煤矿综采工作面支架倒架事故原因,基于该工作面煤层倾角大、地质构造复杂、支架高度大等因素,采用超前预爆破处理顶板、工作面伪斜布置以及安装防倒设施等措施,防止工作面倒架事故发生。通过对24221大倾角综采工作面防倒架措施的改进,保证了该工作面安全开采。In order to prevent the roof accidents occurred when the hydraulic powered support fell down in the fully mechanized coal mining face in the steep inclined seam,the paper studied and analyzed the causes of the hydraulic powered support down in the full mechanized coal mining face of Xinjiang Coking Coal Group.Due to the face seam high inclination,complicated geological,high powered support height and other factors,the pilot pre-blasting roof,the false inclined layout of the coal mining face,anti-falling device and other measures were applied to prevent the powered support falling down accident in the coal mining face.With the improvement of the anti-falling measures for the powered supports in No.24221 fully mechanized coal mining face,the safety mining of the coal mining face could be ensured.
