Problems solved by technology
However, the above two mining methods are suitable for the relatively stable rock mass of the ore body roof. The roof of the field is prone to collapse, causing casualties
At present, for the mining of gently inclined broken ore bodies, the shallow hole falling ore layering and filling mining method is generally adopted. Although this method can safely recover the ore body, the production capacity is usually low, and the mining process has many links and complex processes.

Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with the drawings.
[0026] Such as figure 1 , figure 2 As shown, a subsequent filling mining method suitable for gently inclined medium-thick broken ore bodies includes the following steps:
[0027] (A) Divide the ore body into a panel every 50m along the vertical direction of the ore body, and then divide a mining area every 200-300m along the direction of the ore body in the panel, and use a panel interval between the panels and the panels. Column 1 is used for separation, and the mining areas in the panel are separated by mining area column 2. The width of column 1 in the panel is 30m, and the width of column 2 is 30m. A panel can be divided into 4-5 mining areas. ;
[0028] (B) Arrange the panel trackless roadway in column 1 of the panel section, and arrange the panel ramp at the bottom wall of the ore body. The panel trackless roadway is connected with the panel ramp and is consistent with ...

The invention discloses a subsequent filling mining method suitable for a gently-inclined medium-thick breaking ore body. The subsequent filling mining method specifically includes the steps that orebody division is carried out; a panel trackless gateway is distributed in a panel studding, a panel ramp is distributed on a lower disc of the ore body, a well linking way is tunneled in a mining areastudding, and strip-type first-step stopes and strip-type two-step stopes are arranged in a mining area; in a top cutting linking way, a top cutting gateway is tunneled in the middle portion of eachof the strip-type first-step stopes and the strip-type two-step stopes in the walking direction of the ore body; stoping of the overall mining area carried out in two steps, the strip-type first-stepstopes and the strip-type two-step stopes are mined in a one-spacing-one manner, filling is carried out after stoping of the first-step stopes is finished, and stoping of the two-step stopes is carried out after filling is completed. By means of the subsequent filling mining method, mechanized, safe and efficient stoping of the medium-thick and gently-inclined ore body is achieved under the breaking roof condition, the stope production capacity is greatly improved, the stope production capacity can reach 200-370 t / d, and workers conduct drilling under the roof bolting supporting condition.
Description
Technical field [0001] The invention belongs to the technical field of mine mining, and particularly relates to a subsequent filling mining method suitable for gently inclined medium-thick broken ore bodies. Background technique [0002] The mining of gently inclined ore bodies has always been a problem in the mining industry. Due to the limited conditions of the gently inclined ore bodies, it is difficult to achieve safe and efficient mining in technological links such as rock drilling and mining. In recent years, with the promotion and application of trackless equipment, at this stage, the medium and deep hole room-pillar method and the segmented open field method are mainly adopted for the medium-thickness and gently inclined ore bodies. However, the above two mining methods are suitable for the relatively stable roof and rock mass of the ore body. When the roof of the ore body is relatively broken, such as the medium and deep hole room-pillar method or the segmented open fiel...
