基于气压计基点测定法,介绍了海天煤业通风阻力测定的方案布置和计算理论依据。通过对现场测定数据的计算和分析,结果表明:进风段、用风段、回风段的通风阻力占总阻力的比例分别为16.4%、39.1%、44.5%,矿井等积孔为2.4 m2,矿井通风难易程度为容易。针对回风段阻力比较高的情况及测定过程中容易产生的误差,根据现场实际情况分析了原因,提出了合理的建议。
Based on the base point measurement method of barometer, the scheme arrangement and calculation theory basis of Haitian coal industry ventilation resistance measurement are introduced. Through the calculation and analysis of field measurement data, the results show that the proportion of the total resistance in the inlet air section, the use air section and the return air section are 16.4%, 39.1% and 44.5% respectively, and the equivalent hole in the mine is 2.4 m2 , Mine ventilation is easy. Aiming at the situation that the resistance of return air section is relatively high and the error that is easy to occur in the measurement process, the reason is analyzed according to the actual situation in the field and a reasonable suggestion is put forward.
