摘要： There is disclosed a process for the extraction of thick coal seams by means of which coal seams not extractable in one bank or slice and/or located at peripheral areas may also be extracted under improved mine safety conditions and with high productivity.According to the invention the thick coal seam is if required, divided horizontally and/or vertically into extraction blocks which are bounded and separated by stowing pillars arranged according to the direction of advance of the extraction. The cavity of the pillars is advanced at a level higher than the level of the roof of the extraction space, after which the cavity of the pillar is back-filled. Then the block is extracted by means of block caving in a manner known per se. In a preferred embodiment of the invention incombustible material that agglomerates under the effect of the static pressure of the rock is used for stowing.The utilization of the process for extraction according to the invention results in a considerable increase of intensity. Whether the extraction is in one or more slices and whether using individual or self-advancing supports, using track-bound or independent loading/conveyor equipment, an economic extraction of coal seams is achieved.
摘要翻译：公开了一种用于提取厚煤层的方法，通过该方法可以在改进的矿井安全条件下以高生产率提取在一个或多个切片中和/或位于周边区域的煤层。根据本发明，如果需要，厚煤层水平地和/或垂直地划分成根据抽出方向排列的收集柱而界定和分离的提取块。支柱的空腔前进到高于提取空间屋顶的高度，此后立柱的空腔被填充。然后通过块本身以本身已知的方式提取块。在本发明的一个优选实施方案中，在岩石静压作用下聚集的不燃材料用于收集。利用根据本发明的提取方法导致强度的显着增加。是否采用一个或多个切片，以及是否使用单独的或自行推进的支撑，使用轨道或独立的装载/输送设备，实现煤层的经济提取。
