为更好地评价井下通风网络,优化矿井通风系统.将示踪气体技术应用于特定复杂的通风网络,并对示踪气体在巷道内的移流扩散规律进行模拟计算.通过对兴阜矿示踪气体浓度实测数据与模拟数据的对比,对巷道理论计算风速和弥散系数进行有效修正,使推导出的在多条巷道内示踪气体浓度的理论计算公式及结果更加符合井下实际情况.在此基础上进一步分析检查实验矿井通风系统中存在的问题,明确漏风区域的具体位置,为通风系统优化及井下工作环境安全规划提供可靠的理论根据.
In order to evaluate the underground ventilation network better and optimize the mine ventilation system, the tracer gas technology is applied to the complicated ventilation network, and the migration and diffusion regularity of the tracer gas in the roadway is simulated.According to the trace of Xingfu Mine Gas concentration measured data and simulation data compared to the theoretical calculation of wind speed and dispersion coefficient of the effective correction so that the theoretical calculation of the gas concentration in the multiple laneway theoretical formula and results more in line with the actual situation downhole.Based on this Further analysis and examination of the existing problems in the experimental ventilation system of the mine clarifies the specific location of the air leakage area and provides a reliable theoretical basis for the ventilation system optimization and safety planning of the underground working environment.
