永城矿区新庄矿是正在建设中的现代化矿井,它位于黄淮冲积平原,冲积层厚140～160米,山西组二2煤为主采煤层,其次为三3煤。三3、三5煤等局部可采煤层。 井田为一简单的单钭构造,地层倾向北北西至北北东,倾角8～10度,深部变缓为4～5度。东邻安徽省刘桥矿,西以王庄断层为界,南部为露头。据覆盖层底部取芯所获资科21个孔有15个孔为粘性土,平均厚17米,一般粘塑性较强,可起到隔水作用。而南中部、东南部及南端靠近露头处杆流砂及砂砾层,地表水易补给风化带。风化带裂隙一般含水性弱。据301孔抽水资料:单位涌水量0.023升秒/·米,渗透系数0.118米/日。新生界下部为粘上,粉细砂和泥钙质胶结的砂卵砾石含水层。据403孔抽水资料:单位涌水量0.00798升/秒·米,渗透系数0.229米/日。
Yongcheng Mine Xinzhuang Mine is a modern mine under construction. It is located in the Huanghuai alluvial plain with alluvial thickness of 140-160 meters. Shanxi Formation 2 and 2 are the main coal seams, followed by San 3 coal. Three 3, three 5 coal and other local mining coal seam. Minefield is a simple single ridge structure. The strata tend to be north-northwest to north-north east with a dip angle of 8 to 10 degrees and a deep slowing to 4 to 5 degrees. Liuqiao mine east of Anhui Province, West Wangzhuang fault as the boundary, the southern outcrop. According to the bottom of the core layer obtained by the acquisition of 21 subjects hole hole 15 holes for the clay, an average of 17 meters thick, generally strong viscoplastic, can play a role in water. The south central, southeastern and southern ends of the outcrops near the flow of sand and gravel, surface water recharge weathering zone. Weathered zone fissures are generally weakly watery. According to 301 holes pumping information: Unit inflow 0.023 liters / m, permeability coefficient of 0.118 m / day. The lower part of the Cenozoic is a sand, gravel aquifer that is cemented with fine silt and calcareous cement. According to 403 holes pumping information: unit inflow of 0.00798 liters / s · m, the permeability coefficient of 0.229 m / day.
