| 摘 要： | 瓦斯抽放是我国治理瓦斯灾害的主要措施,目前抽放率较低.采用控制爆破技术进行提高瓦斯抽放效果的研究,解决了在高瓦斯煤层爆破的安全起爆、长水平炮孔中的装药技术和炸药品种的选择等问题.爆破后瓦斯自排量较非爆区提高5倍以上,抽放率提高明显,抽放时间缩短1/3以上.

| Abstract: | Gas pre-drainage is the main solution to solve gas disaster problems.The efficiency of gas pre-drainage,however,is low by far.The method of controlled blasting was investigated to improve the ef- fect of gas pre-drainage.Such problems as safe ignition in high-gas coal bed,charging technique in a long horizontal borehole,and selection of explosives were solved.After the blasting,the amount of gas self- drainage is more than 5 times that in the non-blasting area,the efficiency of gas pre-drainage is improved, and pre-drainage time is less than 2/3 of the original time. |
