Embodiment
[0037] This embodiment relates to a method for mining vanadium ore with steeply inclined ore and rock crushing in combination with machine guns. In this embodiment, the parameters of the above-mentioned mining area are as follows:
[0038] Ore body dip angle: greater than 45°;
[0039] Block strike length: 200m ~ 400m;
[0040] Middle section height: 25m;
[0041] Pillar width between adjacent ore blocks: 8m ~ 10m;
[0042] The height of the pillars between the middle sections: less than or equal to 5m;
[0043] Layer height: 10m;
[0044] Bottom roadway 1 width: 3.5m;
[0045] Height of bottom laneway 1: 3m;
[0046] Depth of blasting fan-shaped medium-deep hole 9: 7m;
[0047] Blasting length: 6m each time.
[0048] It includes the following steps:
[0049] Mining area layout:
[0050] Divide the ore body into a middle section every 25m in the vertical direction, and divide an ore block every 200-400m along the strike, leave 8-10m inter-pillars between the ore blocks,...

The invention provides a method for breaking steep dip ore rock and mining vanadium ores by using machinery and powder for jointly mining and relates to the technical field of mining. The method for breaking steep dip ore rock and mining vanadium ores by using machinery and powder for jointly mining comprises the following steps: dividing middle sections at 25m intervals along vertical direction of ores, wherein each middle section is divided into an upper layer and a lower layer, a through tunnel is arranged on the bottom of the lower layer and a cantilever excavator is adopted for mining; withdrawing the cantilever excavator after the ending of mining in the through tunnel; forming fan-shaped medium-length holes on one end of two tunnels inserted into the ores; exploding the upper layer,thereby breaking and falling the ores on the upper layer onto the upper layer and lower layer; using a crawler loader and a mining carrier vehicle for outputting ores on the upper layer; exploding the lower layer, and then using the crawler loader and the mining carrier vehicle for intensively outputting residual ores on the lower layer. According to the method for breaking steep dip ore rock andmining vanadium ores by using machinery and powder for jointly mining, the manner of exploding layer by layer, outputting ores in layers and stages and intensively outputting ores is adopted for solving the technical problems of bad blasting effect of once explosion, high ore mining difficulty and low mining efficiency in the prior art.
Description
technical field [0001] The invention relates to the technical field of mining, in particular to a vanadium ore mining method of steeply inclined ore rock crushing in combined mining with machine guns. Background technique [0002] Shangluo City, Shaanxi Province, my country has relatively large reserves of vanadium ore resources. The vanadium ore in this area is mainly carbon-siliceous rock sandwiched with mudstone-type vanadium ore, with well-developed joints and fissures. The firmness coefficient of the surrounding rock is 4-6, and the average thickness of the ore body is 15m. , with an average inclination of 72°. The roof rock of the ore body is composed of dolomite, (calcium swarf) sandstone, and thin-bedded carbon-siliceous rock, and the floor rock is composed of medium-thin layered carbon-bearing limestone interbedded with mudstone or yellow-brown mudstone. At present, the mining method adopted by most mines in this area is the low-stage vertical roadway fan-shaped dee...
