| Abstract: | Huaibei mining limited company Zhuxianzhuang coal mine primary mineable coal bed the eighth coal, average thickness is 9.98m. But exploitation conditions are complex,coal seam is very flaccidness, and the coal seam dip angle on the partial exceed 40°.By taking measures, include strengthening roof management,guaranteeing the stability of the supports and the pre and post scraper conveyor. Preventing the coal spontaneous combustion and ignition, we recovery enhancement in maximum. We realized safety and high efficiency fully-mechanized caving of the large inclined angle, flaccidness, extra thick and inflammable coal seam. |
