综放开采是解决厚煤层开采难题的有效途径

Fully mechanized top coal caving mining is the effective access to solve difficult problems in thick seam mining

我国厚煤层储量丰富, 但是其赋存条件复杂, 如何有效地解决我国厚煤层开采技术难题,一直是采矿专家们关注的问题。20多年来, 在我国发展成熟的综合机械化放顶煤开采技术, 以其技术先进、投资少、消耗少、效率高、安全性好的五大特点, 将厚煤层的储量优势转化为经济优势, 已成为我国厚煤层采煤方法改革和解决难采厚煤层技术难题的有效途径, 取得了显著的技术经济效果。介绍综放技术在解决我国不同矿区难采厚煤层的应用情况及其取得的技术效果。

The coal reserves of thick seam are rich in China. But the geological deposit conditions are complicated. How to effectively solve the technical problems of thick seam mining in China has been a problem concerned by the Chinese mining experts. The fully mechanized top coal caving technology with the features of advanced technology, less investment, less consumption and high efficiency developed in China has turned the advantage of the thick seam reserves to a economic advantage and have become a effective access to the reform of the thick seam mining method in China and solve the technical problems in the thick seam mining. Obvious technical and economic results have obtained from the fully mechanized top coal caving mining technology. The paper mainly introduced the application and technical results of the technology to solve the difficult thick seam coal mining in different coal mines.
