An introductory text and reference on mining engineeringhighlighting the latest in mining technology Introductory Mining Engineering outlines the role of the miningengineer throughout the life of a mine, including prospecting forthe deposit, determining the site's value, developing the mine,extracting the mineral values, and reclaiming the land afterward.This Second Edition is written with a focus onsustainability-managing land to meet the economic and environmentalneeds of the present while enhancing its ability to also meet theneeds of future generations. Coverage includes aboveground andunderground methods of mining for a wide range of substances,including metals, nonmetals, and fuels. Completely up to date, this book presents the latest information onsuch technologies as remote sensing, GPS, geophysical surveying,and mineral deposit evaluation, as well as continuous integratedmining operations and autonomous trucks. Also included is newinformation on landscape restoration, regional planning, wetlandspr

本书以人为干预为主线,耦合自然过程,以喀斯石漠化综合治理示范区为单元,从研究人为干扰下的石漠化过程机理和人为干预下的石漠化生态征出发,以石漠化生态恢复的人为干预响应为核,揭示不同地貌背景、不同社会经济发展、不同生态恢复治理工程干预下石漠化的演变机制;通过对多尺度、多类型喀斯生态系统的观测集成研究,综合分析诊断化及恢复生态系统的健状况及演进趋势,揭示受人为干预的喀斯生态系统结构和功能的基本征和自维持机制及其对石漠化过程的影响,生态综合恢复措施时空化调控过程与配置模式的化度,提出调控措施。
