【摘要】：山体浅埋煤层采空区漏风复杂,地表裂隙难以治理,易于造成采空区煤体自燃,而瓦斯与火共存条件下增大了火区治理难度。通过合理优化选取注氮、注浆、堵漏风等综合防灭火技术措施,对CO异常进行了治理,最后取得了显著的效果,提高了矿井的安全开采水平。
[Abstract]:The air leakage in the mined-out area of shallow buried coal seam in mountain is complicated and the surface fissure is difficult to control. It is easy to cause spontaneous combustion of coal body in the goaf, but it is more difficult to control the fire area under the condition of the coexistence of gas and fire. Through the rational selection of comprehensive fire prevention and extinguishing measures such as nitrogen injection, grouting and air plugging, the CO anomaly has been treated, and remarkable results have been obtained, and the level of safe mining in the mine has been improved.
