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。

There are a large number of tailings and waste rock and other solid waste emissions every year in the development and use of the Mineral resources.

摘 要：矿产资源在开发、利用的过程中，每年都有大量的尾矿、废石等固体废弃物排放。

At present, the multipurpose use of gangues and tailings retrieved useful elements and material transferred at home and abroad.

目前，国内外主要从物质再回收和物质转移两个方面对废石和尾矿的综合利用进行研究。

The mathematical relationships among mixed layer thickness, ore recovery and waste dilution against drawpoint spacing, volume per drawing, cut-off waste dilution and level interval are studied in details. It shows that the contact face between ore and waste as a ideal interface is incorrect during drawing.

以二次回归正交放矿计算机仿真实验为研究手段，以单一采场放矿为研究对象，详细地阐明了混杂层厚度、矿石回贫指标与漏斗间距、一份放出量、截止废石混入率及阶段高度之间的数学关系；研究指出：在放矿过程中，将崩落矿岩接触带视为一理想界面是不正确的。

Thinking comprehensively of geological environment, ecological and nature environment, making surely the contents and emphasis of the environmental quantity assessment, establishing the index system of the environmental impact assessment and its ratings standard, studying the evaluation theories and its methods of the EQA, revealing time-space variety regulation of environmental quantity, studying the time-space distributes regulation of mineral pit water、waste heap eluviate water, tailingspile waste water and its heavy metals pollution and migration rules in surface water, groundwater, water department bottom mire, soil, applying division form R/ S analysis to research the development trend of heavy metals monitors data in water and soil, using mathematical statistics, gray theories, neural network, fuzzy evaluation, time order analysis to establish the forecast model of the EQA in mine geotechnical system.

综合考虑系统内地质环境、生态环境、自然环境，确定矿山岩土工程系统环境质量评价内容与重点，创建矿山岩土工程系统环境质量评价指标体系及其分级标准，研究矿山岩土工程系统环境质量评价理论和评价方法，揭示矿山岩土工程系统环境质量时空变化规律，研究矿坑水、废石场淋滤水、尾矿库废水时空分布规律及其引起的地表水、地下水、水系底泥、土壤等重金属污染及迁移规律，应用分形R／S分析研究水土监测时间序列发展趋势，再用数理统计、灰色理论、神经网络、模糊评价、时序分析等建立岩土工程系统环境质量预测模型。

Based on the current condition of Henan aluminum soil recultivation, we located an empty and waste area after exploited at Xiaoguan Mine of Changcheng Aluminum Industrial Company and carried out a series of experiment and research on soil recultivation there in terms of engineering recultivation, biological recultivation and soil ripeness.
