摘要
以矿山井下矿柱的实际形态为基础，建立了模拟测试方法和理论分析基础，提出了实用抗压强度这一概念，从而奠定了“自然支护法”在三下采矿工程中应用的理论和实践基础。
it is an important research objective of mining rock mechanics that the actual compressive stregth of pillars is analysed accurately and quantitatively. This paper, based on the real formation of pillars in an underground mine,sets up the imitative testing method and theoretical basis for analysis, puts forward a conception, that is,practical compressive strength, and lays, therefore, a theoretical and practical foundation which will contribute to applying self-supporting openings to the underground mining engineering.
