摘要
应用综放工作面通风理论和瓦斯涌出与运移规律,结合大水头煤矿高瓦斯易燃特厚煤层综采放顶煤开采特点,通过实例分析,论证了新型通风技术(B型)在特大瓦斯涌出综放工作面开采中应用的技术合理性、安全可靠性、经济高效性。
With the ventilation theory and gas emission and migration law in fully mechanized caving mining face, the paper showed the technology rationality, safety reliability and economic efficiency of the new ventilation technology applied in the fully mechanized caving mining face with ultra high gas emission in combination of the features of fully mechanized caving mining in high gas emission and spontaneous combustion thick seam and the analysis of practical causes.
