对煤体结构形态及成因分类的改进和完善

为便于理论研究和矿井生产中煤与瓦斯突出预测时的应用、资料积累和对比,参照构造岩的分类方法,依据煤体结构的宏观特征和不同煤体结构类型煤的物性参数的测定结果,在对原煤体结构四类分法做了较大补充的基础上,根据非接触性探测煤体结构类型的需要,提出了硬煤和构造软煤的煤体结构二类分法,其中硬煤与原生结构煤、碎裂煤相对应;构造软煤与碎粒煤、糜棱煤相对应,从而改进和完善了煤体结构的形态及成因分类.

Improvement and perfect way for the classification of the shape and cause formation of coal body texture

In order to be more convenient for applying, collecting data and making contrast in theoretical study and practice for forecasting outburst of coal and gas, the authors have consulted both of the classification of tectonic rock according to the macro-feature of the coal body texture and the result of determination of physical property parameters to different types of coal body texture. Based on the the supplements for the four-classifications of coal body texture and the need of non-contacting survey of the type of coal body texture, the authors put forward two classifications which are stiff coal and tectonic soft coal. Stiff coal is equal to the primitive texture coal and smash-split coal, and tectonic soft coal is equal to smash-grain coal and powder coal, which improve and perfect the classification of the shape and cause formation of coal body texture.
