Problems solved by technology
[0003] In the prior art, water-soluble mining methods are usually used for salt deposits. Due to the dissolution characteristics of salt deposits, tunnels are generally used to excavate chambers, and cracks are generated by drilling and blasting. The mining method of soaking and dissolving has high labor intensity and high mining costs. High, dangerous operating environment, low recovery rate, causing serious pollution to the environment
This type of operation has low efficiency, high risk, high noise, and high cost, and it is difficult to meet the requirements of sustainable, low-carbon, and environmentally friendly development. Especially when it is close to the town, each blasting is equivalent to a magnitude 3 earthquake, which seriously interferes people's work, study and life

Embodiment Construction
[0025] The salt mine dissolution crack cutting construction method of the present invention adopts tools, equipment and facilities such as diamond wire saw 2, wire saw machine 3 and track 4, in the parallel horizontal roadway 1 of different layers excavated within the scope of predetermined operation area, to The ore body is cut for construction.
[0026] like figure 1 As shown, several parallel horizontal roadways 1 are excavated in the predetermined operation area of the mining area. The length of each horizontal roadway 1 is more than 100 meters, and the cross-sectional size is not less than 2.5 meters×2.5. Two square cutting bodies up and down are produced, and the technical scheme of the invention is further explained by taking the cutting operation of the lower cutting body as an example:
[0027] 1. Between the upper, lower, left and right horizontal roadways 1 of the lower cutting body, use the theodolite to determine the drilling position, and drill the left and ri...

The present invention discloses a construction method for cutting solution fissures of salt ores, which includes steps as follows: excavating parallel horizontal tunnels in a range of pre-setting operation area, the horizontal tunnels locate on different layers; and cutting out pre-setting solution fissures on ores by using tools, devices and facilities such as a diamond wire saw, a rope saw machine, tracks and so on in the horizontal tunnels. The present invention provides the underground mining of solute type salt ores with a novel mining method which is safe, environmental protective, efficient and inexpensive.
Description
(1) Technical field: [0001] The invention relates to the mining of underground salt ore bodies, in particular to a construction method for cutting and dissolving cracks in salt ore. (two) background technology: [0002] Salt ore bodies mostly refer to rock salt, Glauber's salt, trona, potassium salt and other mines. [0003] In the prior art, water-soluble mining methods are usually used for salt deposits. Due to the dissolution characteristics of salt deposits, tunnels are generally used to excavate chambers, and cracks are generated by drilling and blasting. The mining method of soaking and dissolving has high labor intensity and high mining costs. High, dangerous operating environment, low recovery rate, causing serious pollution to the environment. This type of operation has low efficiency, high risk, high noise, and high cost, and it is difficult to meet the requirements of sustainable, low-carbon, and environmentally friendly development. Especially when it is close t...
