摘要
长距离掘进巷道通风路径较长,传统风筒在传输风量时面临较大的风阻,存在漏风量大等问题,导致工作面进风和排风困难,这既需要解决瓦斯和粉尘问题,又要确保合理利用能源。基于此,文章通过采用局部通风技术,排出开采释放出的有害气体及爆破作业产生的烟雾和各类粉尘,旨在保障巷道作业区域的环境舒适度。实际应用结果表明,应用该技术具备显著的经济效益和环境效益,证明了该技术的可行性。
The ventilation path of long-distance tunneling roadway is long,the traditional air duct faces large wind resistance when transmitting air volume,and there are problems such as large air leakage,which leads to difficulties in air intake and exhaust in the working face.This requires to solve the problems of gas and dust and to ensure the rational use of energy.As a result,this paper uses local ventilation technology to discharge the harmful gases released by mining and the smoke and various types of dust produced by blasting operations,aiming to guarantee the environmental comfort of the roadway operating area.The practical application results show that the application of this technology has significant economic and environmental benefits,proving the feasibility of the technology.
