孟庄煤矿位于闸河煤田北部肖县境内,地面自然标高为+33.5～+34.0米,第四纪冲积层厚度一般为34～40米,自地表向下2.0～2.6米为粉砂,其余为粘土、砂质粘土、粘土夹砂礓等互层,以砂质粘土为主。中间夹两层流砂,第一层流砂在垂深4.5米左右,层厚约0.5～0.7米,呈灰黄色,粘塑性较差,透水性强;第二层在垂深12米左右,厚度约0.7～0.9米,呈浅黄色,以中粗砂为主,含黑色铁锰结核较多,涌水较大。
Mengzhuang Coal Mine is located in Xiao County in the northern part of Zhahe Coalfield. The natural elevation of the ground is +33.5 ~ +34.0 meters. The Quaternary alluvium thickness is generally 34-40 meters. The surface is 2.0-2.6 meters down from the surface and the rest is Clay, sandy clay, clayey clays and other layers of clay to sandy clay-based. The middle sandwiched between two layers of sand, the first layer of sand in the vertical depth of 4.5 meters, layer thickness of about 0.5 to 0.7 meters, grayish yellow, poor viscoplasticity, water permeability; the second layer in the vertical depth of about 12 meters, the thickness of about 0.7 to 0.9 meters, pale yellow, mainly in the coarse sand, black ferromanganese nodules with more water gushing larger.
