Mining of very thick seam with inclined slicing method by using wire-mesh and water jet for cutting top coal

本文以试验工作面地质概况、工作面参数及装备、回采工艺及劳动组织、矿压观测及技术经济效果分析等几方面进行了较为详细的叙述.

This is one of the methods for mining thick coal seam. The Hydro-mining Research Institute of Tangshan Branch of CCMRI made a commercial test in Hebi NO.6 Colliery in cooperation with Hebi Mining Administration. The trial lasted one more year with satisfactory results. In the trial period, the best monthly production was 30, 126 t, the best daily production 1, 890 t, the best face OMS 12.6 t. The paper described in detail geology of test face, face parameters, equipment, mining technology, labor organization, observation of ground pressure, and techno-economic results.
