新郑矿区位于新郑县城西北部,勘探区面积约120公里~2。本矿区主要可采煤层为二_1煤、一_1煤。太原群中发育的G_3L_(7-8)和C_3L_(1-4)两层段灰岩,分别为二_1煤的底板和一_1煤的顶板,是这两层煤的直接与间接充水含水层。因此,搞清这两层灰岩的岩溶发育特征,将会为今后建井、开采选用有效的防治水方案提供依据。
Xinzheng Mining Area is located in the northwestern part of Xinzheng County, with an exploration area of about 120 km ~ 2. The main mining coal seam for the two _1 coal, a _1 coal. The limestone of two layers of G_3L_ (7-8) and C_3L_ (1-4) developed in Taiyuan Group are the bottom plate of No.1 and No.1 coal and the top plate of No.1 coal respectively, which is the direct and indirect filling of these two layers of coal Aquifers. Therefore, to clarify the karst development characteristics of the two layers of limestone will provide the basis for the future construction of wells, the selection of effective water control programs.
