Abstract: It is not clear that the difference of mechanical properties between the weakly cemented strata in the West- ern mining area and the strata in the Middle Eastern mining area. Therefore,this is the fundamental cause of the fre- quent occurrence of disastrous accidents in the mining process of the western mining area. The distribution of weakly cemented strata was studied on the coal mine area in China. The weakly cemented rock physical and mechanical data of six typical mines of Xinjiang and Ordos mining area were chosen. Also,the parameters of density,porosity,moisture content,elastic modulus, compressive strength, tensile strength, cohesion, internal friction angle, Poisson ratio with depth variation regularity were analyzed. The results show that the weakly cemented strata are mainly distributed in Xinjiang region,Ordos basin and Eastern Mongolia mining area in China. The degree of rock formation was not suffi- cient,thus the rock strength was generally low. In Western mining area,the lithology mainly included sandstone,sandy mudstone and mudstone. The rock density and depth was positively correlated,and the rock density was positively line- arly increased with the increasing depth. The porosity and moisture content were negatively correlated with the increas- ing depth. The elastic modulus,compressive strength,tensile strength and cohesion had a certain linear increasing cor- relation with the increasing depth. In addition,Poisson ratio,internal friction angle had not obvious correlation with the increasing depth. The strong disintegration of weakly consolidated rock is the main factor that causes the height of wa- ter-conducting fracture zone to increase. The strength of weakly cemented rocks in Western mining area was lower than that of the same type rock in Middle Eastern mining area. It could further clarify the difference between rocks in the Western mining area and in the Eastern mining area with the establishment of the set of rock physical and mechanical properties.
