摘要
以4206综采工作面为工程实例,对沿空留巷工作面通风系统可靠性进行分析,采面采用沿空留巷技术后,由于松散三角区范围显著降低,采面漏风量得以明显减少;采面通风效率有所提升,通风风阻分布情况更为合理。结果表明,沿空留巷工作面通风系统较为可靠,可以确保采面生产需要。
Taking 4206 fully mechanized mining face as an engineering example,the reliability of ventilation system along the goaf roadway is analyzed.After adopted the technology of the goaf roadway,the air leakage of the mining face is obviously reduced because of the significant reduction of the loose triangle area.The results show that the ventilation system is reliable and can ensure the production of mining face.
