摘要
特厚煤层开采过程中需要对采空区进行煤层自燃防治工作,均压通风技术不仅可以减少局部通风时漏风量,起到火灾防治的作用,还能通过风流调控影响空气中有害气体及氧气的浓度。本文通过均压通风技术在水峪矿61119工作面的应用,联合注氮、阻化剂等方式对煤层的自燃进行防治,同时调控采区内风流和风压,为井下回采工作提供良好的作业环境。
In the process of extra thick seam mining, it is necessary to control the spontaneous combustion of coal seam in goaf, the equalizing ventilation technology can not only reduce local ventilation time, but also reduce local ventilation, air leakage has played a role in the prevention and control of fire.It can also affect the concentration of harmful gases and oxygen in the air through air flow control. In this paper, the application of equalizing ventilation technology in the 61119 working face of the Shuiyu coal mine is presented, prevention and control of spontaneous combustion of coal seam by combined nitrogen injection and inhibitor, control the air flow and wind pressure in the mining area at the same time, it provides a good working environment for underground mining.
