摘要： 为掌握亭南煤矿302综放工作面开采对两巷的超前影响范围和强度，对超前支护方式的合理性进行评价，通过超前支护支架立柱的工作压力监测分析以及工作面巷道变形量观测分析，确定了302综放工作面超前影响范围约为25m，工作面开采对两巷距工作面10m内的巷道影响较大。现场观测巷道整体变形量比较小，最终确认302综放工作面超前支护方式合理。

Abstract: In order to master the influence range and intensity of minging to the two-gates of Tingnan coal mine, to evaluate the reliability of the support in advance, based on the work pressure monitoring analysis of the support in advance and the observation and analysis of the deformation of the two channels, this paper get the influence range of the 302working face to the two-gates is 25 meters, and the working face has a larger influence to the two-gates within 10 meters, and the overall deformation of the roadway is relatively small. Finally confirmed that the support in advance of Tingnan 302 fully-mechanized working face is reasonable and reliable.
