摘要:
为了进一步探究高抽巷抽采瓦斯效果,对高抽巷的最佳抽采层位进行分析。以常村矿为例,基于紧贴实际采空区碎胀系数分布的“O”型圈理论,依据采空区瓦斯的运移规律,运用FLUENT软件加载自定义UDF对采空区瓦斯分布进行数值模拟,从上隅角瓦斯浓度与抽采浓度2方面,对不同层位高抽巷的抽采效果进行分析,确定高抽巷的最佳层位,并用现场测试数据对数值模拟结果进行验证。研究结果表明:模拟计算结果与现场实测数据基本吻合,所提出的高抽巷最佳抽采层位的确定方法可有效应用于实际;合理的抽采层位不仅能够有效地降低上隅角瓦斯的浓度,而且能够提高抽采的效率。
Abstract:
In order to further explore the effect of gas drainage with the high drainage roadway, the optimal drainage horizon of the high drainage roadway was analyzed. Taking Changcun mine as an example, based on the “O” ring theory closing to the distribution of broken expansion coefficient of the practical goaf, the numerical simulation on the gas distribution of goaf was carried out through loading the selfdefined UDF with the FLUENT software according to the migration laws of gas in the goaf. The drainage effect of high drainage roadway with different horizons was analyzed from the aspects of gas concentration at upper corner and drainage concentration, then the optimal horizon of the high drainage roadway was determined, and the results of numerical simulation were verified by using the field test data. The results showed that the results of numerical simulation were basically consistent with the field measured data, and the proposed determination method of the optimal drainage horizon for the high drainage roadway could be effectively applied in the practice. The reasonable drainage horizon can not only reduce the gas concentration at upper corner, but also improve the drainage effect.
