摘要

It has been 30 years since the classic Coal Mining Technology: Theory and Practice was published, and much has changed in the coal mining industry during that time. The energy provided by coal mining is still essential to human welfare, but the mine operating environment is dramatically different. Surface mine production has doubled, and scientific knowledge about mining has advanced. New information technologies have attracted public attention to mining disturbances, and global competition requires more efficient operations. There are almost 363 billion t (400 billion st) of coal reserves in the United States, but reclaiming this supply has become more challenging because of deeper deposits and the impact of environmental regulations.
