Chapter 2 Monolithic Design of Mining Methods Section 1 Main Contents of Monolithic Design

Once the mining method is selected, the monomer design of the mining method can be carried out. There are two forms of stope design: one is the design department, the standard ore mining method design for the preliminary design, which is a standard solution for the juice, which is the information provided by the geological exploration report. It is summarized as a representative nugget, designed according to the structural conditions of representative nuggets, and the other is the mining method construction design of specific nuggets, including real coordinates, reserves, grades, etc., after production prospecting, Designed on the basis of a tomb that achieves Class B exploration accuracy (for complex! Exploration type ore bodies and remotely dispersed small ore bodies, the level can be reduced according to the specific situation). The construction design of the ore block is a regular technical work in the mining production department. The quality of the design is not only directly affecting the recovery of resources, the quality of mining ore and the cost of mining, but also the safety of production personnel and equipment. , labor intensity and the effect of ventilation and dust.

The design of the stope should be carried out on the basis of the overall design of the stope at this stage. The relationship between the upper, lower, left and right adjacent stopes should be taken care of and the order of recovery should be followed. The mining design of the mining room should also include the mining design of the pillar.

Monolithic designs generally include two major parts: the acquisition and the recovery design. The design of the mining design is the structural design of the ore block, and the design of the mining is mainly the process design. Different mining methods have different design priorities and deep differences. For example, deep hole, medium and deep hole mining methods, deep hole, medium and deep hole design, large blast design, mining method for ore mining under the cover rock, mining design, etc., only like shallow hole mining The mining method, because of its simple content, is a general monomer design.

The design of the stope should generally include: the basis for the selection of mining methods, the determination of the structure and parameters of the stope, the layout of the stope, the construction sequence and schedule requirements, the mining, mining and filling, roof management, ventilation and safety measures, Reduce ore loss, depletion measures and major technical indicators.

At the same time, the following drawings should be completed _: the overall layout of the mine and the pillar, the layout of the mining and cutting works, the sectional view of the main roadway, the supporting structure drawing, the layout of the blasthole, the construction schedule, the engineering scale and the operation. Cycle chart. In addition to the design specifications, the large blasting design shall also provide relevant drawings such as the charge structure and the blasting network.

The contents of the technical and economic indicators should include: geological minerals, geological grades, mining volume, ore and mining grades, ore loss rate, depletion rate, precision cutting, ergonomics, production capacity, main materials Consumption and operating costs, etc.
