文中分析了热兹卡兹甘矿应用房柱法开采缓倾斜和倾斜互层矿体中矿柱与间层的应力状态和失稳的各种形式及其影响因素，提出了保证矿柱稳定性的工程计算方法和保持矿柱同轴性的原则。
In this paper, the various forms and influencing factors of stress state and instability between pillars and interlaminar strata in the mining of gently inclined and inclined interbedded ore bodies in the Hotzkazgan Mine using the method of room-pillar are analyzed. The stability of the pillars is proposed Engineering calculation method and to maintain the principle of ore column coaxial.
