【 摘 要 】

At present, Northwest Jiaodong of a mine has entered the operating environment of-1030m, which is one of the few gold mines in China that have entered the kilo meter operation. The preliminary exploration shows that the mine reserves are abundant and the grade is ideal at about-1500m. However, with the continuous deepening of the ore-body to the deep, the underground pressure is increasing, and the mining difficulty is also increasing, which brings a lot of difficulties to the deep mining. Many problems need to be studied urgently, and the measurement and calculation of ground stress becomes one of the urgent problems in deep mining. Through accurate measurement of in-situ stress, the design and exploitation of deep wells can be carried out scientifically, so as to avoid the harm caused by pressure enhancement.
