摘要
针对大同矿区坚硬顶板垮落难题,提出了利用二氧化碳致裂技术来治理坚硬顶板的方法,通过在塔山煤矿8218工作面进行二氧化碳致裂坚硬顶板的试验,结果表明二氧化碳致裂可取得与传统炸药爆破相当的效果,提高了放顶的安全性。
In view of the hard roof collapse problem in Datong mining area, the method of harnessing hard roof with carbon dioxide cracking technology is put forward. Through the experiment of carbon dioxide cracking hard roof in the 8218 working face of Tashan Coal Mine, the results show that the carbon dioxide cracking can achieve the equivalent effect with the traditional explosive blasting, the security is improved.
