This detailed book systematically investigates subsurface geological fractures using rock mechanics, geology, and geophysics. Based on geological fracture mechanisms and fracture boundary conditions, it presents new finite-difference equations for the simulation of seismic wave responses to geological fractures, and proposes innovative AVO inversion equations for the accurate estimation of the rock properties of the fractured medium. It employs schematics, snapshots, color images and charts to demonstrate the mechanical characteristics of the fractures, the seismic wave-field response to the fractures, the seismic data attributes of the fractures and the rock properties of the fractures obtained via inversion. It provides a new methodology for enhancing geological fracture detection technology and for the accurate delineation of fractured reservoirs that ultimately benefits reservoir and mining engineers, geologists and geophysicists in terms of optimizing reservoir recovery, well performance and mining safety.

Professionals and students in any geology-related field will find this an essential reference. It clearly and systematically explains underground engineering geology principles, methods, theories and case studies. The authors lay out engineering problems in underground rock engineering and how to study and solve them. The book specially emphasizes mechanical and hydraulic couplings in rock engineering for wellbore stability, mining near aquifers and other underground structures where inflow is a problem.

This book comprehensively covers many aspects of green mine, including the basic situation of green mines, mine facilities, extraction management, ecological environment, scientific and technological innovation, standardized management, environmental protection inspectors, and special tools in response to the needs of green mine construction, assessment, and management. It is highly informative with valuable techniques and tools providing insights both for scholars and practitioners working in green mine field.

This book focuses on green mine evaluation. It includes green mine evaluation methods, evaluation content, evaluation indicators, etc. The "Green Mine Evaluation Index" has been issued by the Ministry of Natural Resources of China. In order to promote mining enterprises, green mine consulting service agencies, third-party evaluation agencies and mining administration personnel to better understand and practice the provisions of green mine evaluation indicators, the authors wrote this "Interpretation of Green Mine Evaluation Index". The content of this book specifically includes introduction, prerequisites for green mine selection, score sheet of green mine construction, related knowledge, as well as introduction of specific green mine evaluation items, including mining area environment, resource development methods, comprehensive utilization of ore resources, energy saving and emission reduction, technological innovation and smart mines, corporate management and corporate image, etc. The relevant concepts, relevant laws and policies, implementation measures, inspection points, and materials that enterprises should provide, have been vividly expounded based on the actual situation and specific cases of green mine construction. This book is useful as a reference for managers, engineering and technical personnels, teachers and students from mining enterprises, government departments, consulting services and evaluation agencies, colleges and secondary professional schools.
