产能提升情况下矿井瓦斯涌出规律研究

Study on mine gas emission law under improving production capacity condition

以山西高河能源有限公司3煤层地勘瓦斯参数为基础,以现场实测瓦斯参数为依据,通过对地堪数据进行修正,采用实测值与地勘数据相结合的方式,综合分析了产能提升情况下矿井瓦斯涌出规律,建立了3煤层瓦斯赋存规律数学模型。依据《矿井瓦斯涌出量预测方法》(AQ1018—2006),采用分源预测法,对掘进工作面、回采工作面、盘区、矿井等瓦斯涌出量进行预测,得出各区域瓦斯涌出最大值。通过对瓦斯赋存规律的研究,为矿井在产能提升情况下制订相应的瓦斯治理措施以及今后的矿井瓦斯抽采设计提供了重要参考,也为矿井瓦斯治理提供了更可靠的依据。

Based on gas parameters in geological exploration of No.3 coal seam in Shanxi Gaohe Energy Company,combined with the ac-tual measurement data and geological prospecting date,data of geological exploration were adjusted,comprehensive gas emission law was analyzed under the condition of promoting production capacity,mathematical model of gas deposit law for No.3 coal seam was also estab-lished.Based on ＂Mine Gas Emission Prediction＂（AQ1018—2006）,with the application of sub-source prediction method,gas emission quantity of the heading face, mining face, panels and other mine were predicted, the maximum gas emission quantity were obtained. Through the study of the gas deposit law,it can provide important reference and reliable base for mine gas control in the conditions of promoting production capacity and the design of gas drainage in future.
