由于在世界范围内适于用地下开采的厚煤层贮量极其丰富,所以人们自然把精力集中到解决开采厚煤层的技术及其发展问题上.虽然缺少厚煤层贮量的精确数字,但其贮量无疑是相当大的,可能占全球总贮量的30～40％.对厚煤层的开采无论过去,或现在,仍然需要解决开采损失异常高、井下自然发火、顶板控制、生产不集中和生产率低的问题.因此,寻求一种理想的采煤方法即产量高、经济、安全相一致的采煤方法,至今尚无结果.虽然曾出现过一些方法和工艺,但这些方法和工艺至今仍然没有取得进展.
Naturally, due to the extremely abundant reserves of thick coal seams suitable for underground mining in the world, it is natural that people focus their attention on solving the problem of technology and development of thick seam mining. Although the exact number of thick coal seams is missing, Is undoubtedly quite large and probably accounts for 30-40% of the world’s total reserves.If past or present mining of thick coal seam still needs to solve the problems of abnormally high mining loss, natural downhole fire, roof control, inefficient production and productivity Low.Therefore, to find an ideal method of coal mining, that is, high yield, consistent economic and mining methods have not been achieved.Although there have been some methods and processes, but these methods and processes so far still no make a progress.
