东四采区一段30#层工作面由于大断层的存在,导致工作面严重的不等长,工作面的最大长度与最小长度相差达9米多,工作面被迫进行开上、下帮回采,同时由于大断层的存在,工作面需采过五条空巷,进行三次初采、两次末采,为了最大限度地回收煤炭资源,被迫改变巷道布置,进行液压支架的两次回撤和两次安装同时还要进行工作面液压支架、刮板输送机的对接,经过精心组织、科学管理,采取科学适用的技术措施,一方面回收了煤炭资源,另一方面为今后开采类似工作面积累了可供借鉴的宝贵经验,创造了较高的经济效益,且取得了安全无事故的显著成绩。
Due to the existence of a large fault, a section of 30 # face in Dongsai mining area resulted in a serious unequal length of working face. The difference between the maximum length and the minimum length of working face was more than 9 meters. The working face was forced to open the upper and lower back At the same time, due to the existence of a large fault, the face must adopt five empty lanes, three initial acquisitions and two final acquisitions. In order to maximize the recovery of coal resources, forced to change the roadway layout, two retractions of the hydraulic support and two While installing the hydraulic support face, scraper conveyor docking, after careful organization and scientific management, to adopt scientific and applicable technical measures, on the one hand, recycling of coal resources, on the other hand for the future mining similar to the work area tired The valuable experience that can be borrowed has created high economic benefits and achieved notable achievements in safety and accident prevention.
