摘要
测定了矿井大气压力分布,设计并采用合理的均压防灭火技术方案,抑制了东荣二矿16#煤层工作面煤柱自燃,确保了十七层三面支架的顺利回撤。
By measuring atmospheric pressure distribution in Dongrong No. 2 coalmine, a fairly reasonable fire preventing and extinguishing plan with air pressure balancing technique is designed, which prevented the fire in 16# coal seam from developing successfully and safeguarded withdrawing of mining equipments in workface 3 in the 17# coal seam.
