开采4～8 m急斜煤层,采用F3200/17.5/27F型放顶煤液压支架,运输顺槽选用轻型转载机SZB-630/30。由于放顶煤液压支架长度(前、后)7 645 mm,再考虑前架扩巷炮掘工作面不影响转载机爬坡段,故对转载机SZB-630/30进行改装。为保证前移转载机时水平装载段不歪斜,在转载机与放顶煤液压支架间设移动导轨。
Mining 4 ~ 8 m steep coal seam, the use of F3200 / 17.5 / 27F caving hydraulic support, transport slot selection light reloading machine SZB-630/30. Due to the length (front and back) of the caving coal supporter, 7 645 mm, the re-loader SZB-630/30 is retrofitted after considering that the working face excavation of the roadheader is not influencing the climbing section of the loader. In order to ensure the forward loading machine when the horizontal loading section is not skewed, set the moving guide between the transfer machine and caving coal hydraulic support.
