摘要:
应用能位测定法和示踪检测技术联合检测了鸡西老二井火区地下漏风状态。通过测试计算相对总压值得出了火区范围内井巷系统与采空区的风流关系,进而定性确定了火区内老二井与胜利井之间存在的可能漏风路径。在此基础上,利用瞬时释放示踪气体法确定了胜利井和老二井间的漏风方向和漏风速度,计算得出了火区下采空区内平均直线漏风风速为013m/s,漏风量为776m3/min。研究结果为矿区采取针对性的防灭火措施提供依据,并为同类问题的解决提供参考。
Abstract:
Combining energy level measurement with tracer technique, the air leakage in Laoerjing fire zone was tested. By testing and calculating the relative total pressure in the mine ventilation system, the airflow relationship between laneway and goaf was obtained, and the possible air leakage passageway between Laoerjing shaft and Shengli shaft was found. Moreover, the direction and speed of the air leakage were determined by the instantaneous release of tracer gas test, with the result that the average straight line leakage air speed in the goaf under the fire zone was 013m/s and the leakage ratio was 776m3/min. The results can be used to help the fire extinguishment design and can also provide references to similar situations.
