摘要
针对河南鹤煤十矿12采区1202工作面不稳定煤层工作面支架支护效果问题,通过经验公式确定支架型号,进一步通过现场监测支架阻力以及支护效果,验证工作面支架的安全性。结果表明:ZH2000/16/24F分体顶梁组合滑移液压支架以及DW25-250/100型单体液压柱适用于不稳定煤层工作面,工作面支架来压较平缓工作状态良好,保证了工作面的安全生产。
Aiming at supporting effect of 1202 working face in unstable coal seam in No.12 mining area,No.10 Mine,Hebi Coal Group,an empirical formula was used to determine the type of the support.Further field supervision on supporting resistance and effect verified the safety of the support in the working face. The results show that ZH2000/16/24 F sliding hydraulic support with split beams and DW25-250/100 single hydraulic columns are suitable for the unstable coal seam. Good working condition with smooth weighting could ensure the safe production of the working face.
