为了探索N1102工作面瓦斯治理与配风量之间的关系,通过试验研究分析,利用增阻调节法对N1102工作面的配风量进行了阶梯性调整,得到工作面检修期间不同配风量下的瓦斯治理数据,利用最小二乘法对各项指标数据进行了拟合处理,得出相对应的函数关系,并对函数关系式进行了微积分,得出N1102工作面最适合的风量,为该工作面的风量调整提供了有效依据。通过现场观测,N1102工作面风量调整后上隅角最高瓦斯浓度下降了15.24%,后溜瓦斯浓度下降了11.76%,回风流瓦斯浓度下降了1.3%。
In order to explore the relationship between gas treatment and gas distribution in N1102 working face, the gas distribution of N1102 working face was adjusted step by step by the method of resistance-increasing adjustment through experimental research and analysis, and the gas treatment under different gas distribution during working face maintenance was obtained Data, the least square method was used to fit and process each index data to get the corresponding functional relationship, and the calculus of the functional relation was calculus to get the most suitable air volume for N1102 working face Air volume adjustment provides a valid basis. Through on-site observation, the maximum gas concentration in the upper corner of N1102 decreased by 15.24% and the back-flow gas concentration decreased by 11.76% and the return air flow gas concentration decreased by 1.3%.
