针对自燃煤层及容易自燃煤层矿井掘进巷道顶部的高冒区,以及煤层砌碹巷道冒高处“封闭和半封闭型”漏风,容易发生自燃的情况,利用新型高分子凝胶材料的阻化性能强、渗透性好、吸热量大等优点,通过专用防灭火注浆装置向目标区域压注。实践证明,该材料可有效控制掘进巷道冒高处自燃火灾对矿井生产的严重威胁,能克服传统充填材料性能差、价格高等缺点。
For the spontaneous combustion of coal and easy spontaneous combustion of coal mine tunnel at the top of the tunnel and the high-risk area, as well as the construction of coal seam roadway riser “closed and semi-closed ” air leakage, prone to spontaneous combustion situation, the use of new polymer gel material resistance Strong performance, permeability, heat absorption and other advantages, through a dedicated anti-fire grouting device to the target area injection pressure. Practice has proved that the material can effectively control the roadway heading high altitude spontaneous combustion of the mine a serious threat to production, to overcome the traditional filling materials poor performance, higher prices shortcomings.
