Problems solved by technology
[0004](2) Mining methods and equipment conditions are relatively backward, and the degree of intensive development of mineral resources is low
[0005](3) The traditional, independent and dispersed development mode of small and medium-sized mine groups seriously restricts the improvement of mining efficiency and comprehensive utilization of resources. The utilization rate of roadway development and transportation projects is low, and a large amount of low-grade resources are wasted, the economic benefits are low, and the development is unsustainable, which leads to the plight of crisis mines

Embodiment
[0020] Example : (1) The present invention takes I, II, III three types of ore bodies (groups) and five sub-ores of A, B, C, D, and E as representatives to explain, such as figure 1 with figure 2 shown. According to the distribution of resources in each mining area in the region, analyze the status quo of existing underground transportation systems in five independent mining areas A, B, C, D, and E, and select 2 to 4 main stage transportation lanes that are convenient for connection or the shortest distance. Implementation through. see figure 2 As shown, after adopting this technology, the original E mine stage transportation level roadway 10 has become the main transportation platform 20 in the upper region after the penetration, 18 is the transportation platform in the lower region, and 19 is the transportation platform in the middle region.
[0021] (2) In order to realize the integration of the three major transportation platforms and the vertical engineering of eac...

The invention discloses an intensive mining method of an ore cluster in an ore-concentrated area, belongs to the field of metal mine underground mining, and relates to a method for mining the ore cluster in a wide-range ore-concentrated area. The method comprises the steps of: building middle sections of development transportation platforms communicated with dispersed ore bodies in the ore-concentrated area according to occurrence characteristics of middle-and-small dispersed ore bodies in the area and integrally connecting ore bodies which are independently dispersed; classifying the different kinds of ore bodies; selecting reasonable selected factory addresses; intensively selecting one ore in each selected factory address; concentrating 2-3 middle sections of development transportation platforms and building an intensive rapid transportation platform for members, materials and ores in the area to ensure that the intensive rapid transportation platform is communicated with all underground sub-development transportation systems; partitioning regional mines to build relatively-independent auxiliary production systems in sub-areas for ventilation, power supply, water supply and gas pressing and exhaustion; performing grid-combined connection among the sub-areas; adopting a proper mining method in a unified mode according to the independent ore body characteristics and intensively configuring mechanical trackless tunneling equipment to implement intensive mining and transportation of the ore cluster in the ore-concentrated area. According to the mining method, resources can be integrated, the production efficiency is greatly improved and full recovery of resources and reduction of production cost are realized.
Description
technical field [0001] The invention belongs to the field of underground mining of metal mines, and relates to an ore group mining method in a large-scale ore concentration area. Background technique [0002] One of the main characteristics of my country's nonferrous metal resources is that there are many medium and small deposits and few large deposits. Due to the limitation of the occurrence conditions of scattered medium and small ore bodies, for a long time, many ore-concentrated areas have adopted the independent extensive production mode of small mines and small dressing plants to develop and operate, resulting in complex mining systems, backward mining equipment and low production technology. , the economic benefit is difficult to improve. The main performance is as follows. [0003] (1) The shortcomings of the traditional mining mode of the ore group in the ore concentration area are prominently reflected in the unreasonable allocation of regional resources and min...
