RESEARCH ON THE PHYSICAL AND MECHANICAL PROPERTIES OF BROWN COAL IN BULIANTA COALMINE OF DONGSHENG COALFIELD
东胜煤田补连塔矿煤物理力学特性试验研究

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.
