The developing history and up-to-date state of coal mining methods applied in China’s coal mines sice 1949 have been summarized in this book. Totally 193 tapical examples, which are applied effectively now and of advanced level in China, are collected. Both figures and articals, principally the figures, are shown in the book. More than 300 colour figures and more than 150 colour photos are included. For each example, the general situation, the statement on the application results and the analyses of its applicability are all introduced.
There are six chapters in this book, they are: general comments, roadway layouts of longwall caving ining, mining technology of longwall caving, mining methods in steeply inclined coal seams, other kinds of mining methods, surface mining methods and appendix. The main contents of this book are the introduction of the mining methods applied in state-run coal mines, while several tapical examples of mining methods applied in local government operated coal mines are also collected in it.
