营口县滑石矿所属大岭矿区,系年产3.0万吨左右的小型滑石矿山。1964年投产后,沿用巷道式采矿方式。1968年以来,应用各种简易矿山设备并形成开拓系统,采用效率较高、技术经济效果较好的趋于正规化的采矿方法,使开采规模不断扩大。一、矿床地质赋存条件矿床赋存于白云石大理岩与菱镁岩中,共三条含矿带十个矿体。其中主矿体(第二含矿带的4~#矿体)呈似层状、透镜状产出,连续性差,有明显的分枝、复合、尖灭现象,属Ⅱ—Ⅲ类勘探类型。矿体厚度不均
Yingkou Talian Mine belongs to the large mining area, with an annual output of about 30,000 tons of small talc mines. After put into operation in 1964, follow the roadway mining method. Since 1968, a variety of simple mining equipment has been applied and a pioneering system has been established. Mining methods that are more efficient and have better technical and economic effects and have become more and more standardized have been adopted to expand the mining scale. First, the geological deposit conditions Deposits occur in dolomite marble and magnesite, a total of three ore-bearing belt ten ore bodies. Among them, the main orebody (No. 4 ~ # ore body of the second ore belt) is stratified and lenticular, with poor continuity, obvious branching, compounding and pinchout phenomenon, belonging to Ⅱ-Ⅲ exploration types. Uneven ore thickness
