摘　　要：现如今采矿行业地下工作环境越来越复杂,给施工带来了安全隐患,因此必须要对复杂条件综采工作面切眼支护技术进行优化,保证施工的安全。裕丰公司井田22下02综采工作面布置于两组挠褶带附近,由于顶板受应力影响,在施工切眼时存在大中型冒顶事故的风险,原有支护方案不能满足本工作面的施工要求。因此,对切眼支护技术存在的问题进行分析,提出相应的优化方案,提高施工安全。Nowadays, the underground working environment in the mining industry is becoming more and more complex, which brings potential safety hazards to the construction. Therefore, it is necessary to optimize the cutting support technology of fully mechanized mining face under complex conditions to ensure the safety of construction. The02 fully mechanized mining face under 22 mine field of Yufeng Company is arranged near two groups of flexure belts.Due to the influence of roof stress, there is a risk of large and medium-sized roof fall accidents during construction cutting, and the original support scheme can not meet the construction requirements of this face. Therefore, the problems existing in the cutting support technology are analyzed, and the corresponding optimization scheme is put forward to improve the construction safety.
