Pioneering technology

The basic task of underground mine development design is to determine the location and development system of the main mine shaft. The location of the main shaft affects the positional relationship between the mining industry site and the plant, and has a close relationship with internal and external transportation modes. Different development plans have a great impact on infrastructure investment, operating expenses and construction speed. Therefore, the correct choice of development plan is a very important topic.

There are many factors influencing the choice of the development plan, and the content involved is extensive and complex. In the design, we must adhere to the principle of multiple program selection, and compare them step by step. The choice of development plan should be carried out under the premise of determining the site. Only when the site is difficult to determine, will the comparison work on the development plan related to the site be carried out. The development plan is based on the following principles: advanced technology, can ensure normal and continuous production of the mine; production safety, reliability, upgrading, transportation, ventilation, drainage and other systems intact; make full use of mine resources, leaving no or less security pillars, Reduce losses; less infrastructure construction, low investment, low operating costs, high efficiency; good construction conditions, fast construction, short production time; rational design of underground and ground layout, few links, easy to manage; implementation of relevant national technical and economic policies Try not to occupy or occupy less farmland.
