Example Embodiment

[0030] In order to better describe the present invention, a method of the present invention for safely and efficiently recovering a segmented empty field and subsequently filling a disc interval column of the present invention will be described in further detail below with reference to the accompanying drawings.

[0031] The present invention is a method for safely and efficiently recovering a segmented empty field and then filling a disc section column. On both sides of the disc section column 3, a non-cemented filling body 1 filled with waste rock and a cemented filling body 2 filled with tailings are alternately formed. There are sectional rock drilling roadway 5 and sectional contact road 6 in the column 3 of the panel area, filling retaining wall 4 in the sectional rock drilling roadway 5, and stope slope outside the surrounding rock of the panel area Road 7 is connected to each subsection, and subsection communication channel 6 is respectively connected with stope slope 7...

Abstract

The invention discloses a method for safely and efficiently recovering panel pillars by using a sublevel open-stope subsequent filling method, A sublevel rock drilling roadway (5), a sublevel contact way (6), a stope slope ramp (7) and a sublevel vein-following contact way (8) of an original project are fully utilized, filling raises are arranged at intervals in the length direction of the panel pillars (3) according to design parameters in the upper section of the middle section of stoping, the filling raises are used for backfilling waste rocks to form a filling waste rock covering layer (9) according to the mining principle of a sill-pillar-free sublevel caving method, ore removal is completed under the covering layer, it is ensured that ore rocks in a stope are full, and retaining wall pillars (10) on the two sides are supported, so that the stoping safety is ensured. The method is high in ore recovery rate, high in recovery capacity, low in recovery cost, high in mechanization degree, safe in operation environment, free of goaf after recovery and free of hidden danger.

Description

technical field [0001] The invention belongs to the technical field of underground mine mining, and in particular relates to a method for recovering an interval column of a mining panel by adopting a segmented empty field and subsequent filling method, which can be widely used in underground mining of large and medium-sized non-coal solid mines such as black, non-ferrous, and chemical mines. Background technique [0002] With the improvement of environmental protection requirements, the advancement of filling technology and the reduction of filling costs, more and more mines adopt the filling method for mining, especially iron mines. Due to the relatively thick ore body, whether the stope is arranged along the vein or vertically, the length of the stope is too long, which is not conducive to safe mining. Therefore, the ore deposit is divided into multiple panels, and inter-columns are set between the panels. , the stope is divided in the panel, and the stope connecting roadw...
