Embodiment 1
[0044] figure 1 A schematic diagram of the structure of a panel of a medium-thick ore deposit provided in Embodiment 1 of the present invention; figure 2 for figure 1 The cross-sectional view of A-A in the middle; image 3 for figure 1 The cross-sectional view of B-B in the middle; Figure 4 It is a schematic flow chart of the mining method provided by Embodiment 1 of the present invention.
[0045] Such as Figures 1 to 4 As shown, the embodiment of the present invention provides a kind of gently inclined medium-thick orebody panel filling mining method, including:
[0046] Step S1, the gently inclined medium-thick ore body is divided into mining segments according to the rock drilling depth and ore body inclination angle of the medium and deep hole rock drilling equipment; When the rock drilling depth of the rock equipment is large, the inclination angle of the ore body is large, and the ore rock is relatively stable, the section height should be large, and vice versa...

The invention provides a panel filling mining method for a gentle-dipping medium-thick ore body. Ore blocks in a panel are stoped through two steps and are arranged at intervals, in the first step, the mining blocks adopt cemented filling, and in the second step, the mining blocks adopt tailing filling. The mining sequence of the ore blocks are from top to bottom, the upper ore blocks are stoped firstly, and then the lower ore blocks are stoped. In the panel, an ore collecting funnel is arranged on the lower plate of each ore block in each section, wherein an upper opening of the ore collecting funnel directly faces the lower plate of the ore block, and a lower opening of the ore collecting funnel is connected with the end of a corresponding ore loading access road. Each ore block in eachsection in the panel is provided with the corresponding ore loading access road, wherein one end of the ore loading access road is connected with the lower opening of the ore collecting funnel of theupper adjacent section, and the other end of the ore loading access road communicates with a vein exterior linking passage on the outer side of the section. One end of each rock drilling linking passage communicates with a vein interior rock drilling passage in the corresponding section, and the other end of each rock drilling linking passage communicates with the vein exterior linking passage inthe corresponding section. According to the panel filling mining method, the engineering quantity is few, the efficiency is high, rock drilling and ore removing of the ore body in the sections are conducted in the different sections, thus mutual interference is little, and safety is good.
Description
technical field [0001] The invention relates to the technical field of mining, in particular to a mining method for filling a gently inclined medium-thick ore body panel. Background technique [0002] The gently inclined medium-thick ore body is a difficult-to-mining ore body in underground mines, which is difficult to draw ore and requires a large amount of mining work. [0003] There are two main types of existing gently inclined medium-thick ore body filling mining methods: one is the layered filling mining method, this type of mining method uses shallow hole rock drilling, personnel and equipment work in the stope, and has a wide range of applications. The engineering volume is large, the production efficiency is low, and the safety is poor; the other type is segmental filling mining method, which adopts medium-deep hole and deep-hole rock drilling, and personnel and equipment work in the roadway. The ore blocks in the area are independently excavated in sections, with ...
