摘要
针对铜坑锡矿细脉带１７＾＃采场１６＾＃矿柱，用模拟试验方法研究和分析了爆破动载对该矿柱稳定性的影响，并用现场验证结果修正了动载安全系数，指出爆破动载作用是影响矿柱稳定性的主要方面，从爆破动载的角度提出了设计安全，可靠矿柱的具体要求，建议在设计地下采场矿柱时，不但要考虑静载的作用，而且要考虑爆破动载的作用，相应地提出了与所研究的现场矿柱岩性相适应的具体矿柱设计经验公式，为同类矿体设计提供了科学依据。
Taking some pillars in one mine as examples,the effect is thoroughly studied of explosion dynamic load on pillar stability by means of stimulating test method. The result obtained in the study adjusts the traditi-tonal safety coefficient of explosion dynamic load. The author emphasizes that both static and such dynamic pressures should be taken into consideration when designing safe pillar. He also develops experinental formula for designing pillar.
