褶皱变形系数在煤与瓦斯突出预测中的应用

对以褶皱构造为主要构造型式的突出矿片来说，用褶皱变形系数这一定量指标，通过控制煤和瓦斯突出褶皱构造的研究，在一定程度上能提高突出预测的准确率。本文针对平顶山东矿区煤层褶皱变形的特点，分别用剖面变形系数法和平面变形系数法进行了突出危险性预测研究，取得了较可靠的预测结果。

APPLICATION OF DEFORMATION COEFFICIENTS OF FOLD IN FORECASTING OUTBURST OF COAL AND GAS

For the outburst shaft whose tectonic type is mainly fold,the pass through the study of foldstructure controlling the outburst of coal and gas by the quantiative index of deformation cofficientof fold,to a certain degree,it can raise predictable accuracy of the outburst.According to thecharacteristics of seam fold deformation in the eastern mining area of Pingdingshan,the authorstudies prediction of outburst possibilities respectively by section deformation cofficient and planedeformation coeffcient,and acquires more dependable prediction results.
