Mining section mining technology
The section mining method is based on the division stage, and then the stage is divided into sections, each of which forms an independent mining and ventilation system. During the continuous mining, the temporary top and bottom columns are reserved between the sections, or only the temporary bottom column (or the top column) is retained, so as to be divided into strip-shaped mine houses and pillars along the inclined direction of the ore body, and the first mining room, and at the same time Back to the mining column, but the former maintains a certain distance from the latter. In the case of discontinuous mining, the temporary column is left at a certain distance in the section, and it is divided into several mining units (mines), first mining room, and then mining the inter-column and top column adjacent to the mining room, and at the same time Handling gobs. Applicable conditions One of the important features of this law is that it can effectively control the exposed area of ​​the roof when recovering by relying on reasonable selection of the section height and the structural parameters of the temporary pillar, so it can be used to mine ore and surrounding rock in moderately stable ore bodies. Since each segment has an independent ore-mining system, different ore structures can be used to solve the ore transportation according to different inclination angles of the ore body, and the inclination range of the ore body can be wide, from gentle inclination to steep inclination. However, the mining and cutting engineering of this method is very large. Mainly used for mining ore bodies above medium thickness. When in recent years, in our ferrous metals, non-ferrous metals and chemical mining gently inclined inclined thick ore body above, the Act gained more use and development MeCan Waste Sterilization is used for the waste from hospital, such as: infusion sets, syringes, gauze, bandages, gloves, fabrics, etc, it is can be customized.
