针对21007工作面S型煤流系统传统设备布置方式导致生产过程中大煤量运输时易造成刮板输送机满负荷运行、大煤量情况下刮板输送机易压死、并且刮板链条磨损较快、链条紧固比较困难,检修难度大,运输环节出现卡脖子现象,严重制约了采煤产量的提升等问题,提高煤流系统运输能力进行了分析研究并提出了解决办法,对原有煤流运输设备进行了替换改造,将原有刮板输送机在S弯处选择更换为布置DTL120/55电滚筒带式输送机,并对带式输送机尾架、缓冲架进行改造,调整电滚筒机尾输送带起伏角度。
In view of the traditional equipment arrangement of S-type coal flow system in 21007 working face, it is easy to cause the scraper conveyor to run at full capacity when the heavy coal is transported in the production process. The scraper conveyor is easy to die down and the scraper chain is worn Quicker, more difficult to fasten the chain, overhaul difficulty, kinks in the transport links, problems such as the increase of coal production have been severely restricted, and the transportation capacity of the coal flow system has been analyzed and put forward some solutions. The coal transportation equipment was replaced and rebuilt. The original scraper conveyor was replaced at the S-bend with the arrangement of DTL120 / 55 electric drum belt conveyor, and the tail conveyor and buffer rack of the belt conveyor were modified and adjusted Roller tail conveyor belt ups and downs angle.
