摘要:
为确定综掘面风流智能调控装置的最优调控方案，以优化风流场分布状态来减少粉尘瓦斯聚集，分析选取11项影响通风效果的因素作为评价指标，构建3层结构的调控评价指标体系；利用层次分析（AHP）法确定指标权重，构造基于F分布的各指标隶属函数，应用模糊综合评价法确定各指标的隶属度，计算方案评价分值。针对陕北某煤矿，计算出风口距端面5 m工况所有调控方案的仿真实验数据，确定模型评价指标权重及隶属度函数，通过评价得出最优调控方案。研究结果表明：回风侧行人呼吸带、司机位置粉尘质量浓度分别降低43.1%、68.9%，端面上隅角和下隅角瓦斯体积分数分别降低54.7%、66.8%，从而验证风流智能调控评价模型的有效性。研究结果可为综掘面风流调控方案的确定提供参考。
Abstract:
In order to determine the optimal control scheme of the intelligent wind flow control device for the fully mechanized heading face,and optimize the distribution of wind flow field to reduce the dust and gas accumulation,11 factors affecting the ventilation effect were selected as the evaluation indexes,and a control evaluation index system with 3-layer structure was constructed.The index weights were determined by using the analytic hierarchy process (AHP),then the affiliation function of each index based on F distribution was constructed,and the affiliation degree of each index was determined by applying the fuzzy comprehensive evaluation method to calculate the evaluation score of the scheme.Taking a coal mine in northern Shaanxi Province as an example,the simulation experimental data of all control schemes for the working condition of 5 m from the air outlet to the end face were calculated,and the evaluation index weights and affiliation functions of the model were determined.The optimal control scheme was derived through the evaluation,and the underground measurement analysis was carried out.The results showed that the dust concentration at the breathing zone of pedestrian on the return side and the driver decreased by 43.1% and 68.9%,respectively.The volume fraction of gas at the top angle and bottom angle of end face reduced by 54.7% and 66.8%,respectively,which verified the effectiveness of the evaluation model on intelligent wind flow control.The research results can provide reference for the determination of the wind flow control scheme in the fully mechanized heading face.
