摘要
本文介绍以各向异性岩体力学来研究小铁山矿上部中段的地压活动规律与控制措施所取得的结果。研究结果表明,片岩巷是非对称破坏楔体形态,采用光面爆破成巷、不等强支护体系等措施能有效地解决矿山地压问题和取得较显著的经济效果。
This paper presents the results of our researches on the regularities and controlling measures of ground pressure of above sublevels at Xiaodiesan Mine on basis of the principles of anisotropic rock mechanics. The results have shown that the failure of openings in the schist is of unsymmetric wedge, and that such measures as smooth blasting and unequal strength support etc are effetive in solving the problems of ground pressure of mines, and the Significant economic returns have been achieved.
