前言中国是世界上开发利用煤炭最早的国家之一。但解放前,煤炭工业的发展十分缓慢,一九四九年原煤产量仅3,243万吨。新中国成立后煤炭工业发展迅速,进行了大规模煤田地质勘探,一九八四年煤炭产量达7．72亿吨,居世界第二位。累计完成钻探工程量7,000 Foreword China is one of the earliest countries in the world to develop and utilize coal. However, before the liberation, the development of the coal industry was very slow. In 1949, the raw coal output was only 32.43 million tons. After the founding of New China, the coal industry developed rapidly and large-scale coalfield geological exploration was conducted. In 1984, coal production reached 772 million tons, ranking the second in the world. A total of 7,000 drilling projects have been completed
