煤矿开采枝术是煤炭生产技术的核心。近些年来,我国煤矿开采技术有了很大发展,生产技术面貌显著改观,机械化水平及劳动效率大幅度提高,安全情况改善,涌现出一大批高产综采队、高档普采队,建成了一大批现代化矿区、矿井。煤炭工业的现代化发展已开始迈出了重要的一步。在采煤技术方面,已试验成功一批生产能力大、安全好、效率高的采煤方法,例如,厚煤层分层综采法、一次采高达4.5m的综采法、一次采放高度达15m的放顶煤综采法、无煤柱开采法、“三硬”、“三软”煤层综采法、炮采“三新”工艺,以及“三下”采煤、带(水)压开采等特采技术。同时,长壁工作面机械设备造型、工作面端头支护、合理巷道布 Coal mining technology is the core of coal production technology. In recent years, great progress has been made in China’s coal mining technology, the production technology has been significantly improved, the mechanization level and labor efficiency have been greatly improved, and the security situation has been improved. A large number of high-yielding and high-grade mining teams have emerged and a A large number of modern mining, mines. The modernization of the coal industry has begun an important step forward. In mining technology, a batch of coal mining methods with large production capacity, high safety and high efficiency have been tested successfully. For example, the comprehensive mining method with thick coal seam is adopted. The fully-mechanized mining method with a mining capacity of 4.5m at one time, 15m top-coal caving method, non-pillar mining method, “three hard”, “three soft” coal seam fully mechanized mining method, “three new” Mining and other special mining technology. At the same time, longwall face mechanical equipment modeling, face end support, reasonable roadway cloth
