Problems solved by technology

This typical ramp layout method has the characteristics of large amount of excavation, high excavation ratio, complicated excavation and slag removal process, and high cost of waste rock transfer and filling. However, when the waste rock is lifted out of the well, it does not conform to the concept of waste-free mining. , is also not conducive to controlling production costs

Embodiment Construction

[0017] The following is based on Figure 1 to Figure 3 The specific embodiment of the present invention is further described:

[0018] see Figure 1 to Figure 3 , figure 1 There are 3 stopes in . This embodiment provides a ramp layout method applied to the stope of the upward layered filling mining method, including:

[0019] (1) When using the upward layered filling mining method to return to the ore body, on one side of the stope close to the ore body boundary or the mining boundary 5 to 10 meters away, the switchback ramp 4 is dug upward from the lower horizontal middle roadway 6, The slope of the ramp 4 is less than 20%, and it is connected with each stratum of the stope by a short connecting road 5; a scraper is used for slag removal.

[0020] (2) The ramp 4 is constructed section by section with the rise of the layered mining of the stope until it penetrates the upper horizontal middle roadway 7; the ramp 4 is used as one of the safety passages of the stope and the s...

Abstract

The invention discloses a slope ramp arrangement method applied to an overhand cut-and-fill mining method stope. The method comprises the following steps that when an ore body is stoped by an overhandcut-and-fill mining method, at one side of the stope, a returning type slope ramp is reversely and upwards dug from a lower horizontal middle section roadway; the slope ramp and each layer of the stope are communicated through short communication passages; the slope ramp is constructed section by section along with the rising of layered stoping of the stope until being communicated with the upperhorizontal middle section roadway; the slope ramp is used as the safe passage of the stope and a shovel conveyor transfer layer passage during the stope layered stoping; after the stope layered stoping is completed, the slope ramp is used as a main slope ramp between the upper horizontal middle section roadway and the lower horizontal middle section roadway. The digging and mining ratio is reduced; the nearest filling of the filling waste stone can be realized; important significance is realized for reducing the production cost and realizing the energy-saving environmental-friendly treatmentof the waste stone.

Description

technical field [0001] The invention relates to the technical field of underground mining and filling in metal mines, in particular to a method for arranging ramps in a stope of an upward layered filling mining method. Background technique [0002] In the practice of upward layered filling mining method in metal mines, with the application and popularization of scrapers, the efficiency of stope shoveling operations and excavation and slag removal operations has been greatly improved, and the labor intensity and operating environment have been significantly improved. However, as a kind of large-scale mechanical equipment, in order to facilitate the entry and exit of the scraper and larger parts, a ramp is generally constructed in the solid rock on one side of the stope as the main mining engineering content to penetrate the upper and lower levels. Middle lane. Correspondingly, a series of sectioned entryways, sectioned entryways and ramp connection lanes, layered access road...
