摘要
通过对长钻孔松动爆破技术研究,形成完整的长钻孔松动爆破技术,并运用其对中厚及厚煤层开采留设的煤柱进行处理,改变煤柱受力状态,消除由于煤柱引起的集中应力、冲击矿压、采空区自燃等矿井灾害是解决中厚及厚煤层开采遗留问题的有效技术手段。
Through the long drilling loose blasting technology, a complete long drilling loose blasting technology has emerged . By solving the coal pillars problem of the thick coal bed mining and changing the stress state , the concentration of stress caused by coal can be eliminated , including the rock - burst goaf spontaneous combustion , etc. The solution is regarded as an effective way to deal with the legacy of thick and thick coal bed mining.
