摘要
厚煤层底板掘进巷道时,巷道顶为煤层,开展此种条件下采用锚网索支护的研究与应用,具有十分重要的意义。现以马庄煤矿山西组7号煤层765工作面进风巷为研究对象,通过参数选取、实际检测,总结出合理的参数,具有一定的推广价值。
When the roadway drivage with thick coal seam floor, roadway roof was coal seam, to carry out such conditions using anchor net supporting the research and application of cable had the very vital significance. Took Mazhuang Mine 765working face coal seam of Shanxi group No.7 coal seam into the wind lane as the research object, through the parameters selection and the actual test, the reasonable parameters was summed up, which had a certain popularization value.
