摘要
在分析了目前保护煤柱设计方法中存在的一些问题时,指出了其局限性和克服其局限性的根本途径。在采用临界变形值法没计煤柱时,如何确定煤层上山和下山方向煤柱边界及以设计煤柱时如何确定围护带宽度,进行了分析和讨论,最后提出了较为合理的围护带宽度的确定方法。
In analysing some subjects presently existing in designing protection coal pillar, the limitations and the basic method how to overcome them are pointed out. When adopting the critical deformation value method, how to determine the coal pillar boundary along the uphill and downhill directions of inclined coal seam and how to determine fhe width of protection zone in designing coal pillar are analysed and discussed. Finally, the method for determining a more reasonable width of protection zone is given
