大直径定向钻孔瓦斯治理技术研究
|
摘要
随着矿井的开拓延伸,矿井瓦斯、水、地压及火等灾害进一步恶化,严重影响着矿井的安全高效生产。结合实际地质情况,分析了工作面顶板大直径定向钻孔施工的可行性,计算了定向钻孔的施工层位,并通过现场考察,分析了施工效果、抽采效果、成本等因素。综合研究分析认为,采用大直径定向钻孔抽采瓦斯可以缩短工作面瓦斯治理工期,缓解了工作面接替紧张的局面,减少了瓦斯治理巷道工程量,节约了瓦斯治理工程费用的投入。
With the development and extension of the mine,the mine gas,water,ground pressure and fire disasters further deteriorated,seriously affecting the safe and efficient production of the mine.Combining with the actual geological conditions,this paper analysed the feasibility of large diameter directional drilling construction on the roof of working face,calculated the construction horizon of directional drilling,and through field investigation,analysed the construction effect,extraction effect and cost comparison.Comprehensive comparison showed that large diameter directional drilling on roof can shorten the construction period of gas control engineering on working face,alleviate the situation of tense replacement of working face,reduce the amount of gas control roadway engineering,and save the cost of gas control engineering.
