数量化理论Ⅲ在瓦斯突出预测敏感地质指标筛选中的应用

论述了数量化理论及数量化理论Ⅲ的基本原理,提出了反应标度的概念和计算方法,扩展了原来反应取值的适用范围和科学性。以中马村矿区为研究实例,研究了影响煤与瓦斯突出的地质因素,并采用统计单元划分结合数量化理论Ⅲ的方法,从11个地质因素中筛选出8个瓦斯突出预测敏感地质指标,并据此对中马村矿已采区进行了瓦斯地质区划。实践表明:将数量化理论Ⅲ应用于瓦斯地质学是可行的,为瓦斯突出预测敏感地质指标的筛选提供了新的思路。

APPLICATION OF THE THIRD THEORY OF QUANTIFICATION IN FILTERING SENSITIVE GEOLOGICAL INDICES IN GAS OUTBURST FORECAST

This paper presents the concept and its calculation method of reaction degree based on the essential principles of the quantification, which extends its range of application for the primary reaction with a better scientific analysis. Taking the Zhongmacun mine as an example, the paper adopts the method of combining carving-up statistical cells and the third theory of quantification to screen 8 sensitive geological factors out of 11 geological indices that control coal and gas outburst. Based on the analysis, the regional partitions are made for the gas geology at the Zhongmacun mine. The authors then conclude that it is feasible to apply the third theory of quantification in gas geology, which offers a new insight into the filtering of geological factors for the forecast of gas outbursts.
