The papers in this volume provide a unified approach to the design of underground structures in stratified coal and mineral deposits. They include examples of underground structure design in coal and evaporite mines, and case histories of performance of underground structures.

This book is offered as a contribution to the spread of knowledge and understanding in the field of strata mechanics in coal mining. It is written for professionals in the coal mining industry and students of mining engineering and includes some of the author's own philosophy of coal mine stability.

Covers strata mechanics, numerical methods in geomechanics, water jet cutting and mechanical disintegration of rocks. The preface discusses the option of describing typical interdisciplinarity of geosciences, dealing with the processes induced by human activities in geospere, by the word geonics.

During the last thirty years, the increasing need for extracting coal from new mining fields, especially from unmined protective pillars and seams that are threatened with rock bursts and rock-gas eruptions, has accelerated the development of research in the fundamental mining discipline known as rock mass mechanics or geomechanics. Generally, rock mass mechanics is concerned with rock mass movements and with the phenomena accompanying them. Extensive theoretical, laboratory, and in-situ investigations have resulted in considerable achievements in the field of rock mass mechanics. It is impossible to include all these achievements in a single monograph, and therefore in the present book the author has attempted to contruct a synthetic mathematical description of the rock mass movements and of the strain and stress state induced by mining, in particular when extracting mineral deposits.
