本次年度储量检测工作是在 日语翻译《湖北省神农架林区宋洛磷矿区连连坪矿段2006年度资源储量报告》基础上进行, 整个连连坪矿段, 西起沐浴河, 东至敬子河, 北到后河, 南达2062.0高程点。面积10.1089平方公里, 本次检测范围略小于矿证范围(见附图1)。在此范围内重点对湖北省神农架林区宋洛磷矿区连连坪磷矿(以下简称“连连坪磷矿”)采矿许可证范围内的磷矿资源进行地质测工作, 查明检测区内磷矿层的变化情况, 了解矿山开采现状。通过调查矿山探采巷道对区内磷矿层的揭露, 了解磷矿层的厚度、品位沿走向和倾向变化情况, 以及断层对磷矿层的影响, 估算检测区内已开采消耗磷矿资源储量、保有资源储量以及矿山占用的资源储量情况, 其中, 由于矿山探采巷道的不断深入揭露矿层, 通过采样试验, 对原资源储量类别进行重新划分并估算出资源量。 Lianlianping section of Songluo phosphorite mining area is located 9 kilometer away from the south of Songbai town in Shennongjia forested area and is annexed by Songluo country. The mining area ranges from Muyu river on the west to jingzi river on the east, and from Hou river on the north to 2062.0 elevation point on the south.. The geographical coordinates: east longitude 110°40′05″—110°41′20″, north latitude 31°39′10″—31°42′08″. The traffic condition of the mining area is relatively bad, and only the simple road from Chaoyanglianhua phosphorous mine to Lianghekou goes through the north of the mining area and the road is intersected with Panshui-Xingshan simple road at Lianghekou. It is 5 kilometer away from Panshui eastward to Songbai town and it is about 10 kilometer westward intersecting with 209 national road (referring to Attached drawing1).
该矿段内造成滑坡主要是在露采段和修公路过程中山体在重力作用下产生, 另局部第四系松散堆积物在雨水侵蚀下产生滑坡和泥石流。如在莲莲坪20世纪初曾发生几处滑却步和泥石流现象, 冲毁部分农房、田地; 该区为莲莲坪块段陡崖山顶之坡地, 坡积物为砂土、亚砂土、及砂砾石等物, 厚1—5m, 最厚地段可达10余米, 沿矿层倾向堆积, 可产生滑坡面积为22000m2, 在雨季当其含水量达到或超过饱和状态时上海翻译公司, 亦可产生泥石流, 在今后的矿山生产中需加强地质灾害的监控。
The slide in the ore section was mainly formed because of gravity action of mountain mass in opencast working section and in the course of road construction. In addition partly rain erosion of quaternary system loose deposits may result in land slide and debris flow. Several slides and debris flows happened in the early twenty century in Lianlianping to wash off some houses and fields. The area is of sloping field on the mountain top of steep stiff in Lianlianping block, and the deluviual deposits include sand, sandy loam and sandy gravel etc., the thickness of which is 1-5m, the maximum up to over 10m, and the deluviual deposits are accumulated along with ore bed trend and the slide area is 22000m2 . When water content is up to or over saturation status in rainy season debris flow may also be formed. So monitoring of geological hazard shall be strengthened in the course of mine production from now on. |
