大倾角特厚煤层放顶煤液压支架的研制

Development of Hydraulic Support with Top-Coal Drawing for Inclined Super-thick Coal Seam

介绍某矿煤层地质条件、工作面开采及布置方式等情况,以及大倾角特厚煤层综放液压支架的设计、特点及使用效果。使用结果表明:该支架结构合理,支护性能良好,设备配套性好,年产400万t原煤。

Introduces the geological conditions, coal mining field and deployment of some coal mine, and the design, features and usage of a hydraulic support with top-coal drawing for inclined super-thick coal seam. The practical effects show that the construction and technical performance of the support is well designed. Its assembly complementarity is fine. The output of raw coal has been reached more than 4 million tons within a year.
