煤矿井巷维修 | 2011-8-2 15:05:00

1 必须制定井巷维修制度，加强井巷的维修，保持巷道设计断面，保证通风、运输的畅通和行人安全。（煤矿安全规程第91条）

2 立井井筒维修时，必须编制专项措施。（煤矿安全规程第92条修改）

维修井巷支护时，必须制定安全措施，严防顶板冒落伤人、堵人和支架歪倒。

　　扩大和维修井巷连续撤换支架时，必须保证有在发生冒顶堵塞井巷时人员能撤退的出口。在独头巷道维修支架时，必须由外向里逐架进行，并严禁人员进入维修地点以里。

　　撤掉支架前，应先加固工作地点的支架。架设和拆除支架时，在一架未完工之前，不得中止工作。撤换支架的工作应连续进行；不连续施工时，每次工作结束前，必须接顶封帮，确保工作地点的安全。

　　维修倾斜井巷时，应停止行车；需要通车作业时，必须制定行车安全措施。严禁上、下段同时作业。

3　修复井巷，必须首先检查瓦斯，当瓦斯积聚时，必须按规定排放，只有在回风流中瓦斯浓度不超过1.0％、二氧化碳浓度不超过1.5％、空气成分符合本规范6.2.1.2的要求时，才能作业。（煤矿安全规程第93条）

4　报废的巷道必须封闭，并在井上、下对照图上标明。报废的暗井和倾斜巷道下口的密闭墙必须留泄水孔。

　　从报废的巷道内回收设备、设施，必须制定安全措施。（煤矿安全规程第95、96条合并）
