深井复杂地质条件下中厚煤层巷道高效快支快掘探索

Exploration on High Efficiency and Quick Support, Quick Excavation of Middle-thick Coal Mine Under Complex Geological Conditions

通过131102轨道顺槽快速掘进的实际案例,从支护技术优化、装备性能提升、施工工艺优化三个方面进行攻关,探索深井复杂地质条件下中厚煤层巷道高效快支快掘、降本提效,以期解决煤矿人员不足、生产接续紧张的局面。

Based on the actual case of 131102 track gateway rapid excavation, the paper studies the key problems from three aspects of support technology optimization, equipment performance improvement and construction technology optimization, and explores the efficient and fast support and fast excavation of medium thick coal seam roadway under deep mine complex geological conditions, so as to solve the situation of coal mine personnel shortage and production continuity shortage.
