基于围岩地质条件的急倾斜煤层支护技术的研究

Research on Support Technology of Steeply Inclined Coal Seam Based on Surrounding Rock Geological Conditions

我国西部赋存有大量的急倾斜煤层,急倾斜煤层是西部许多矿井的主要煤层,但急倾斜煤层开采支护技术的研究一直是煤矿开采技术中的难题。根据急倾斜煤层的围岩性质、埋藏机理等地质条件,对现有支架进行分析,通过全新的设计思路,研制出一种新型掩护支架,以适应急倾斜煤层高效、安全的机械化开采需要。

There are a large number of steeply inclined coal seams in the west of China,which are the main coal seams in many mines in the west of China.However,the research on the mining support technology of steeply inclined coal seams has always been a difficult problem in coal mining technology.According to the geological conditions of surrounding rock properties and burial mechanism of steeply inclined coal seams,analyzed the existing supports and developed a new shield support by the new design idea,which can meet the needs of high efficiency and safety mechanized mining in steep coal seam.
