    Alternative Ground Control Strategies in Underground Construction

    Alternative ground control strategies in underground construction Keynote address to be presented by Evert Hoek at an International Symposium on "PRACTICES AND TRENDS FOR FINANCING AND CONTRACTING TUNNELS AND UNDERGROUND WORKS" to be held in Athens, Greece, on 22-23 March 2012 www.tunnelcontracts2012.com/ Alternative ground control strategies in underground construction Evert Hoek Evert Hoek Consulting Engineer Inc., Canada ABSTRACT Underground works vary from shallow urban tunnels to very deep tunnels and caverns in the world’s great mountain ranges. The problems encountered at and between these extremes are entirely different and require appropriate approaches to site investigation, design and construction. The establishment of reliable financial estimates, construction schedules and contract proposals can only be done once a realistic geological model has been prepared and a clear understanding of the likely behaviour of the rock mass and the groundwater conditions has been established. The conditions that control the behaviour of different kinds of excavations in a variety of geological environments are presented in the context of case histories. The aim is to provide project owners, financial managers, insurance companies and contractors with a road map that may assist them in avoiding some of the pitfalls and in considering some of the alternative strategies in the development of underground projects. 1 INTRODUCTION Tunnels have been built for hundreds of years as part of transportation systems for people, goods, water and services. Until the middle of the last century these tunnels were generally small in size and the builders sought out the most favourable geology and topography in which to build them.

    Education Roadmap for Mining Professionals

    Education Roadmap for Mining Professionals December 2002 Mining Industry of the Future Mining Industry of the Future Education Roadmap for Mining Professionals FOREWORD In June 1998, the Chairman of the National Mining Association and the Secretary of Energy entered into a compact to pursue a collaborative technology research partnership, the Mining Industry of the Future. Following the compact signing, the mining industry developed The Future Begins with Mining: A Vision of the Mining Industry of the Future. That document, completed in September 1998, describes a positive and productive vision of the U.S. mining industry in the year 2020. It also establishes long-term goals for the industry. One of those goals is: "Improved Communication and Education: Attract the best and the brightest by making careers in the mining industry attractive and promising. Educate the public about the successes in the mining industry of the 21st century and remind them that everything begins with mining." Using the Vision as guidance, the Mining Industry of the Future is developing roadmaps to guide it in achieving industry’s goals. This document represents the roadmap for education in the U.S. mining industry. It was developed based on the results of an Education Roadmap Workshop sponsored by the National Mining Association in conjunction with the U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy, Office of Industrial Technologies. The Workshop was held February 23, 2002 in Phoenix, Arizona. Participants at the workshop included individuals from universities, the mining industry, government agencies, and research laboratories.

Received: 28 December 2018; Accepted: 5 March 2019; Published: 8 March 2019 Abstract: Both Southern Italy and Central China feature historic rural settlements characterized by underground constructions with residential and service functions. Many of these areas are currently tackling economic, social and environmental problems, resulting in unemployment, disengagement, depopulation, marginalization or loss of cultural and biological diversity. Both in Europe and in China, policies for rural development address three core areas of intervention: agricultural competitiveness, environmental protection and the promotion of rural amenities through strengthening and diversifying the economic base of rural communities. The challenge is to create innovative pathways for regeneration based on raising awareness to inspire local rural communities to develop alternative actions to reduce poverty while preserving the unique aspects of their local environment and culture. In this view, cultural heritage can be a catalyst for the sustainable growth of the rural community.
