砚北煤矿通风阻力测定参数优化及结果分析

Parameters Optimization and Results Analysis of Survey of Ventilation Resistance of Yanbei Coal Mine

基于气压计基点测定法,对砚北煤矿通风阻力进行了测定,测定误差小于5%,同时采用基于WINDOWS的可视化矿井通风网络解算软件进行参数残差调平优化处理,提高参数的可信度,为后期矿井采掘接续下通风网络优化调整提供科学的依据。结果表明砚北矿井通风难易程度为容易;然而,对实际总体通风状况分析评价认为矿井的通风系统处于亚健康状态。对矿井通风系统存在的问题进行了分析并提出相应对策。

Survey of ventilation resistance of Yanbei Coal Mine was done based on air-gauge base point mensuration and the evaluated error was less than 5 % , meanwhile, optimization of parameters of re- sidual leveling was done by adopted visual mine ventilation network solution software which based on WINDOWS, to improve reliability of parameters, provided scientific basis for ventilation network optimi- zation after later mine mining. Results showed ventilation difficult degree of Yanbei mine was easy; but ventilation system of mine was considered at subhealth state based on analysis and evaluation of practical overall ventilation state. Analysis was done on problems existing in mine ventilation system and corre- sponding countermeasures were proposed.
