【摘要】:山體淺埋煤層采空區(qū)漏風復雜,地表裂隙難以治理,易于造成采空區(qū)煤體自燃,而瓦斯與火共存條件下增大了火區(qū)治理難度。通過合理優(yōu)化選取注氮、注漿、堵漏風等綜合防滅火技術措施,對CO異常進行了治理,最后取得了顯著的效果,提高了礦井的安全開采水平。
[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.
