我国综放开采技术及其深层次发展问题的探讨

Fully mechanized longwall top coal caving technology in China and discussion on issues of further development

系统总结了综放开采技术在我国 2 0余年来取得的主要成就 ,以及在相关问题上的结论和认识 ,提出了综放开采下一步应继续加强的理论和技术研究问题 ,最后提出了结合放顶煤开采特点 ,应该在煤与瓦斯共采。

The paper systematically summarized the main achievements of the fully mechanized longwall top-coal caving technology in passed 20 years in China and the conclusion and understanding on the related issues. The paper provided the issues of the theoretical and technical researches to be strengthened in the next step for the fully mechanized longwall top coal caving technology. In combined with the characteristics of the top coal caving, the paper finally pointed that the coal mining with gas drainage, grouting in separated strata and strata bumping should be further researched.
