回风顺槽巷道壁打钻孔抽放瓦斯的应用与分析
pplication and Analysis of Gas Drainage Playing Drilling in the Air Return Way
为了解决潞安温庄煤业有限责任公司所采150301采区由于瓦斯浓度过高而停产的问题，采取了在回风顺槽补打钻孔抽放瓦斯的措施，在对抽放钻孔的抽放参数进行合理设计的基础上，利用在回风顺槽巷道壁打钻孔施工快捷、不影响正常生产作业的特点，最终实现了高瓦斯矿井由于瓦斯抽采系统不稳定而导致上隅角及回风巷瓦斯浓度超限情况下的安全回采。经过现场检验，该项措施简洁、有效，健全了瓦斯抽采系统，为建立稳定的矿井抽采系统提供了一种简单而有效的思路。
he mining area of 150,301 of Wen Zhuang Coal Mining Co., Ltd. Of Luan, Anhui stopped Production because of the high- gas concentration. In order to solve this problem, the measure of drilling holes on the return air way is taken. The Characters of this measure are fast to construct, which won't affect the operations of normal production .On the basis of available design the drainage parameters of drilling holes and under the condition of coal mine gas over the standard limited of upper corner and the return airway gas, which realize the goal of mining safety. Field testing proves that the measure is simple and effective, which has improved the system of mine drainage, and provided a simple and effective idea for establishing a stable system of mine drainage.
