中厚煤层大坡度俯采技术研究

摘要

Yongcheng coal group Chensilou coal mine 21 1 10 fully mechanized working face coal seam is the rep-resentative steep slope underhand mining face and the average dip angle is 2 1 °.Analyzes the problem that using the existing equipment in process of underhand mining,puts forward the solutions and ensures the safety production of working face.Practices prove that using the existing equipment in process of underhand mining is viable.It provides the feasible gist for similar fully mechanized working face of Yongcheng coal group,and accumulates valuable experi-ence.%永煤集团陈四楼煤矿21110综采工作面煤层倾角平均21°，是典型的大坡度俯采工作面。分析了该工作面在使用现有设备俯采过程中遇到的难题，提出了解决方案，保证了工作面的安全生产。实践证明，使用现有设备进行大坡度开采时可行的，为永煤集团类似条件综采工作面的开采提供了可行的依据，并积累了宝贵的经验。
