井下采煤技术及采煤工艺的选择

Selection of Underground Coal Mining Technology and Craft

为科学合理地选择井下采煤技术和采煤工艺,提高采煤效率,降低采煤成本,保证煤炭开采质量,分析了井下采煤的几种主要技术,即柱式采煤法、长壁开采技术、放顶煤开采技术。分析了综合化开采工艺、普通机械化采煤工艺、爆破开采工艺、连续开采工艺的特点和适用条件,指出了选择采煤工艺应注意的问题。应根据实际情况制订合理的开采方案,确定合适的开采技术,保证开采工作安全稳定进行,推动煤炭企业良好发展。

In order to scientifically and rationally select the underground coal mining technology and craft,improve coal mining efficiency,reduce coal mining cost and guarantee coal mining quality,the research analyzes several main technologies of coal mining,i.e.pillar method of working,longwall mining technology,and top coal caving mining technology.The research also analyzes the characteristics and application condition of comprehensive,common mechanical coal,blast and continuous mining technology;and points out the notice of coal mining technology.It is suggested to formulate rational mining scheme according to the situation,determine suitable mining technology,guarantee the security and stability of mining,and promote the good development of coal enterprises.
