MG150链牵引滚筒采煤机是MG150系列采煤机机种之一。于1989年10月在大屯煤电公司姚桥矿7153工作面对该采煤机进行了工业性试验。试验期间最高日产2290t,最高月产50732t,园满完成了工业性试验任务。在姚桥矿工业性试验成功的基础上,该机于1990年3月,在不更换任何其它配套设备的前提下,又使用于徐庄矿7211工作面,替代了MD-150采煤机。该工作面长154m,走向长度830m,中硬煤层,煤层倾角16°～22°,平均18°,采高2.5m,直接顶为0.73m厚的泥岩,底板为4.6m厚的细砂岩。回采期间出现过两条断层,一条最大落差2.5m,一条落差1.5m。断层区域顶板破碎,倾角增大,矸石硬度大,给工作面的顶板和设备管理带来很大困难。配套设备为QY240—0.96/26型液压支架,SGW-630/180G型刮板输
MG150 chain traction drum shearer is one of the MG150 series shearer models. In October 1989 in Datun Coal and Electricity Company Yaoqiao 7153 work face to face the shearer industrial test. During the trial, the highest Nissan 2290t, the highest monthly output of 50732t, Park completed the industrial test mission. On the basis of the successful industrial test of Yaoqiao Mine, the machine was again used in 7211 face of Xuzhuang Mine in March 1990, replacing the MD-150 shearer, without changing any other ancillary equipment. The working face is 154m in length and has a strike length of 830m. The medium-hard coal seam has an inclination of 16-22 ° with an average of 18 ° and a height of 2.5m. The direct top is 0.73m thick mudstone and the bottom is 4.6m thick fine sandstone. During the mining there have been two faults, a maximum drop of 2.5m, a drop of 1.5m. The roof of the fault area is broken, the inclination angle increases, and the hardness of the waste rock is large, which brings great difficulties to the roof and equipment management of the working face. Supporting equipment for the QY240-0.96 / 26-type hydraulic support, SGW-630 / 180G-scraper
