This paper probes into mining mode of metalliferous deposit based on the viewpoint of industrial ecology, in the hope of improving resources efficiency, eliminating the four big hazard sources which can bring negative environment impact due to mining of metalliferous deposit, avoiding "end-treatment" engineering needed when mine are closed, keeping integrated mine's ecosystem in the process of mining metalliferous deposit.

Chapter 2 is to discuss features of geological environment in mine, including its structure, existence environment, and boundary condition and slope's stability. Restrict reaction of geological environment to mining is stressfully studied.

第二章讨论了矿山工程这一特定工程背景下地质环境的特性，分别从地质环境的建造特征、结构特性、赋存环境、边界条件、边坡的稳定性等方面对地质环境进行了深入而具体的研究，重点讨论了地质环境对于矿山工程制约作用。

Then a wasteless mining design for a large underground copper mine is discussed.

Some examples are given. Some methods and fruits of the tech-economic evaluation for mining projects are used as reference. The re-evaluation of mineral resource is briefly introduced. It is detailed to convert the mining flotsam into resource. The paper presents a new method, comprehensive index method, to evaluate the actualization degree of wasteless mining.

文中借鉴了矿山项目技术经济评价方面的方法与成果，对矿产资源的再次评价及矿山废料资源化评价进行了讨论：提出了应用综合指数法对无废开采实现程度进行评价的理论体系；应用神经网络系统对矿业可持续发展进行评价，建立了相应模型及标准。

If there is enough gold in the deposit to be produced economically, a mine is permitted and loped.
