Description

technical field [0001] The invention provides an experimental instrument and an experimental method for mining inclined medium-thick and thick ore bodies by a caving method, and relates to the technical field of caving method simulation experiments. Specifically, it provides an experimental instrument and an experimental method for simulating "the mining process of inclined and sharply inclined medium-thick ore bodies and thick ore bodies". Background technique [0002] Caving mining method is a low-cost, high-efficiency large-scale mining method. It is characterized in that: the entire ore block is used as a mining unit, and the mining is carried out continuously according to a certain mining sequence; during the mining process, the ore is placed under the overburden rock; as the ore collapses, the surrounding rock is forced (or naturally) collapsed Fill gobs to control and manage ground pressure. [0003] For caving mining, a simulation device is usually used to design t...
