潘一矿煤体结构特征及其在煤和瓦斯突出预测中的应用

煤体结构是煤与瓦斯突出的主要因素之一。利用钻孔测井曲线特征并结合矿井地质构造成果，对淮南潘一矿8煤层煤体结构特征及其构造煤发育规律进行了研究。研究表明该矿区8煤层构造煤发育，其厚度大于该煤层厚度20％的点数占一半以上，因其顶、底板围岩封闭性良好，有利于瓦斯聚集，易在采动条件下发生煤与瓦斯突出，确认为该区煤与瓦斯突出的重点煤层。依据瓦斯始突深度、构造煤分层厚度大于0．5m的分布范围、大中型断层位置及矿井突出资料，在F4断层组的两侧分别圈出了煤与瓦斯突出的危险区和威胁区。

Panji No.1 Coalmine Coal Mass Texture Features and Their Application in Coal-and-gas Outburst Prediction

Coal mass texture is one of the main factors of coal-and-gas outburst. By the use of borehole logging trace characteristics combined with mine geological structure research results, studied the No.8 coal seam coal mass texture features and tectonoclastic coal developing pattern. The study has demonstrated that tectonoclastic coal is well developed in No.8 coal seam in the mine area, 20% enumerations with their thickness greater than coal seam thickness account for more than half. Since the closure of roof and floor adjoining rocks is quite good and favor to gas accumulation. Thus coal-and-gas outburst is easy to happen during mining, confirmed that the No.8 coal seam is the emphasis of coal-and-gas outburst in the area. According to outburst starting depth, distribution range of tectonoclastic coal with layering thickness 〉0.Sm, large and medium fault positions and coalmine outburst data, cycled out coal- and-gas outburst danger zone and threatening zone on both sides of the F4 fault respectively.
