The Maoping tungsten-tin deposit is located in the eastern section of Nanling metallogenic belt, the Chongyi-Dayu-Shangyou tungsten polymetallic ore concentration area and at the front part of the Tianmenshan rock mass extension with a north trend. Greisen and the quartz vein are the main tungsten-tin mineralization types in the mine area.

茅坪钨锡矿床位于南岭成矿带东段，位于崇－余－犹钨多金属矿矿集区西华山－杨眉寺区段中北部的天门山－红桃岭矿田，为天门山岩体向北倾伏延伸的前锋部位；矿区钨锡矿化类型主要有云英岩型和石英脉型两种。

Firstly, the stope vacancy was monitored using CMS, taking cavity measured data as foundation, cavity three-dimensional model of the stope opening was created using Surpac software and gain the stope three-dimensional configuration and the actual boundary accurately. Then, the stope designed model and ore-rock interface digital terrain model were established according to the stope design material. Finally, using ore-rock interface DTM to cut cavity model or through Boolean calculation among the models, ore remains, mining total volume, mullock, backfilling, pure ore and dilution rate of stope N3-4 were calculated accurately, thus the large-scale stope mining index visible calculation was realized effectively.

采用CMS探测三维采场空区，以空区实测数据为基础运用Surpac构建采空区三维可视化模型，获取采场空区的三维形态和实际边界；运用采场设计资料，建立采场回采设计模型及矿岩边界模型，通过模型间的布尔运算，计算出采场存留矿量、回采总体积、采下废石量、采下充填体量、采下纯矿石量、回采总量及回采贫化率等，从而有效地实现了大规模采场回采指标的可视化计算。

In this deposit, ore bodies exist in the stratoid form and are c ontrolled by thrust faults. The host rocks are limestone in Bolila Formation of Late Triassic Jiezha Group and in Gadikao Formation of Early-Middle Permian Kaix i nling Group, with strong dolomitization and weak silicification. Minerals are ra ther simple and consist of sphalerite, galena, pyrite, calcite, dolomite and barite. The important ore textures are colloforms such as framboid and crust and xenom orphic grains, and the ore structures are in disseminated, brecciated, veinlike and lumpy forms.

分析了柳河安口镇—头道沟一带区域地质背景以及金矿化地质特征，作了区域地球物理场研究和地球化学场分区，初步总结出本地区的主要控矿因素，并对今后在该区进一步找矿作了一些探讨。

A quantitative appraisal of the prospect of uranium mineralization is completed based on a set of hydrochemical data acquired from the known in-situ leachable sandstone-type uranium, including radon content, acid-alkali ratio, oxidized and reduced electronic potential, hydrocarbonate radical and uranium content in water.

但是在找铀过程中仅用水化学成份、氡含量、酸碱度和氧化还原电位等数值进行描述，说明它们与铀矿化的关系，这种单一因素的描述不能综合反映与铀矿化的联系程度，以定量评价铀矿化与上述因素的关系，从而影响了水化学找矿的效果。
