煤炭开采技术创新展望

煤炭开采业目前是以井工开采固体形态的原煤产品为主。近阶段世界各主要采煤国正在加大对煤层气开采的研究和试验 ,煤层气开采有望成为煤炭采掘业的重要组成部分。煤炭地下气化目前尚处于试验研究阶段 ,如果取得技术上的突破 ,煤炭采掘业中 ,洁净的气体产品比重将大幅度提高

Prospect of the Innovation of Coal Mining Techniques

At present, the coal mining industry takes the raw coal with solid shape mined in the pit as the dominant product, and in the near period of time, all major coal mining countries in the world are paying great attention to the research and test on the mining of coal bed gas that is hopeful to become the important component of the coal mining industry. The coal underground gasification is still in testing and researching phase right now, and if it obtains the breakthrough technically, the ratio of the clean gas products will be increased greatly in the coal mining industry.
