东胜煤田补连塔矿煤物理力学特性试验研究

RESEARCH ON THE PHYSICAL AND MECHANICAL PROPERTIES OF BROWN COAL IN BULIANTA COALMINE OF DONGSHENG COALFIELD

详细研究了东胜煤田补连塔矿煤的岩石组成、内生裂隙及外生节理的发育特征。测试了煤的抗压强度、抗拉强度及载荷位移全过程曲线。东胜煤田褐煤的力学强度较中国其它地区褐煤高，煤的物理力学特性呈十分明显的各向异性，煤的物理力学特性与应力条件有关。

The maceral, proximate analysis, cleats and joint developmental characteristics of the brown coal in Bulianta coalmine, Dongsheng coalfield have been studied. The physical and mechanical properties, compressive and tensile strength and the relationship between load and displacement, have been tested. The mechanical strength of the brown coal in Dongsheng coalfield is higher than that of other brown coal in China. There are very close relationships between the stress conditions and the mechanical properties of brown coal.
