白音华一号露天南帮工程地质特征分析

Analysis of Baiyinhua No.1 Surface Coalmine South Slope Engineering Geological Characteristics

在分析矿区地层岩性、构造和水文地质条件的基础上,依据岩石的物理力学性质,确定了矿区边坡的软弱层面,同时对矿区南帮(非工作帮)的工程地质特征进行了研究。认为:第四系松散层具饱水性质,新近系地层以膨胀性的粘土(岩)为主,可塑性较强,易崩解,抗压、抗剪强度低,煤系地层以软岩为主,力学强度亦低,矿区工程地质特征为二类一型。据此预测了该区可能产生的工程地质问题,并提出了相应预防措施。

Based on mine area strata lithological, structural and properties found out weak seams on mine slope, meanwhile, hydrogeological condition analyses, according to rock mechanical studied surface mine south （non-working） slope engineering characteristics. Considered that the Quaternary loose beds are saturated, Neogene strata are mainly swelling clay （claystone） with strong plasticity, easy to disintegrate and low compressive strength and shear strength; coal measures strata are mainly soft rocks, also low in mechanical strength, thus engineering characteristics can be classed under category Ⅱ, type 1. On these grounds, possible engineering geological problems in the area are predicted, corresponding prevention measures put forward.
