摘要
根据田陈煤矿3下采区煤层厚薄差异大,埋藏深度深的地质条件,研发ZF9000放顶煤和一次采全高两用支架,研究了相应的开采工艺和顶板控制措施,提高煤炭回收率,对我国煤炭工业的持续、稳定发展都有重大意义。
According to the geological conditions the thickness difference and the buried depth of 3 coal seam in Tian Chen coal mine, develop ZF9000 dual-purpose bracket of caving and full-seam mining, and study the corresponding mining and roof control measures, improve the coal recovery rate, which have a great significance to the sustained and stable development of China＇s coal industry.
