Embodiment Construction
[0024] The present invention will be further described below in conjunction with accompanying drawing and working principle:
[0025] like figure 1 and 2 Shown is a method for improving mining efficiency in underground stopes, which includes the following methods:
[0026] A: Set up measures to mine out facilities: On the basis of the normal layout of the stope connecting roadway 8 outside the vein, the mine shaft outside the vein 6 and the talent well 11 outside the vein, there are a number of mining roadways 1 in the stope, and the mining roadway 1 and the middle The blasting place of deep hole 5 is connected, and the middle position of recovery roadway 1 is provided with measure contact roadway 2, and measure contact roadway 2 connects each recovery roadway 1, and measure slip mine shaft 3 is set at the two ends of measure contact roadway 2, and described measure slip The mine 3 is connected with the middle transportation roadway, and the lower end of the mine shaft 3 is ...

The invention discloses a method for improving the ore production efficiency of an underground stope. On the basis of an outside-vein contact roadway, an outside-vein ore chute and an outside-vein personnel and material well, a plurality of mining roadways are arranged in the stope; the mining roadways communicate with a medium-deep hole blasting place; a measure contact roadway is arranged at themiddle positions of the mining roadways; each of the mining roadways communicates through the measure contact roadway; measure ore chutes are arranged at two ends of the measure contact roadway; themeasure ore chutes communicate with a middle section transportation roadway; and vibration ore drawing machines are mounted at the lower ends of the measure ore chutes; according the invention, through the arrangement of the measure contact roadway, the measures ore chutes, lump ore storage chambers and a slag road surface, the transportation distance is shortened, the working time is increased, the walking speed of transportation equipment is increased, and the ore production efficiency is significantly improved; compared with a traditional ore production method, the ore production efficiencyis increased from 45 to 50 tons per machine-team to 120 to 130 tons per machine-team.
Description
technical field [0001] The invention belongs to the technical field of mining, and in particular relates to a method for improving the mining efficiency of an underground stope. Background technique [0002] The mining efficiency of the underground stope is related to the mining blasting effect, mining equipment, road conditions, transportation distance, and operating time. When the blasting effect and mining equipment are fixed, it is related to the road surface conditions, transportation distance, and operating time. [0003] In the traditional downward sub-caving mining method, the out-of-vein connecting roadway 8, the out-of-vein mine shaft 6 and the out-of-vein talent well 11 are arranged in the stope, and mining is carried out from top to bottom according to the height of the segment. Arrange out-of-vein contact roadways outside the ore body boundary, and arrange out-vein mine shafts at intervals of 50m on the out-of-vein contact roadways. The ore extraction equipment...
