Solution mining
Solution mining entails the injection of brine solutions into underground potash-bearing or other salt seams. The solution dissolves soluble potash-bearing minerals from the seam, and the pregnant potash-bearing Horizontal Line Drive (HLD) selective solution mining is a new technology for selectively solution mining potash by utilizing proven oilfield technologies from Steam Assisted Gravity Drainage (SAGD) and Horizontal Line Drive Selective Solution Mining Methods

Class III Injection Wells for Solution Mining US EPA
Class III well types. Class III wells are used to mine: Uranium. Salt. Copper. Sulfur. More than 50 percent of the salt and 80 percent of the uranium extraction in the United States involve the use of Class III injection wells. Uranium in-situ leaching (ISL) is the most common method by which uranium is extracted in the United States.@article{osti_649382, title = {HORSMIC.

Mechanism of collapse sinkholes induced by solution mining
In salt mining, the salt caverns formed by solution mining may lead to collapse sinkhole disasters. Predicting and preventing this type of sinkholes is a real and urgent problem. In this paper, three collapse sinkholes at the Dongxing Salt Mine were taken as examples to investigate the collapse mechanism of overlying strata above salt solution mining, a hole of 12mm diameter and 35mm length was drilled centrally into the block. The hole was filled with a mixture of saline water and magnesia cement a composite commonly used to fixate pipes in large bore holes during un-derground salt exploration mining. A 1=400tubing was cen-trally encased into the concrete.Lab scale salt caverns first results on construction and

Collapse mechanism of the overlying strata above a salt cavern by
In solution mining of salt formations, unreasonable salt cavities formed may lead to surface collapse hazards. In this paper, a mathematical model was proposed to analyze the collapse mechanism of the overlying strata above a salt cavern induced by solution mining with double-well convection. In the proposed model, the collapses of Adapted from ‘tight oil’ horizontal drilling used in the Saskatchewan oil patch, our technology, Horizontal Line Drive (HLD) Selective Solution Mining, is a capital-friendly and environment-friendly way of mining potash.

Drift mining horizontal shafts dug into the earth; Slope mining (ISL) mining, this technique can be used to extract mineral resources that are soluble in water. In solution mining hot water is forced into mineral ore followed by compressed air. The air causes the solution of hot water and dissolved mineral ores to rise to the surface.They thought insoluble interbeds in solution mining could result in “bottleneck” in the cavity, FLAC software, but this study did not explain the detailed mechanical theory for kinds of failure, and the influence of horizontal stress on roof collapse also could not be introduced in their study.Stability of interbed for salt cavern gas storage in solution mining

Salt Cavern Construction Control SpringerLink
As the height of the residues increases, the position of the central pipe needs to be gradually raised during the solution mining process of constructing a salt cavern gas storage space. In order to ensure the formation of a salt cavern with a regular shape, it is necessary to maintain a proper two-end distance, so the position of the Therefore, numerical simulation becomes an alternative way to obtain the solution mining process for TWH caverns. Since the 1960s, great progress has been made in the field of numerical simulation of solution mining for UGS (Kunstman and Urbanczyk, 2000). For instance, a series of commercial cavern leaching simulation codes have been Numerical model and program development of TWH salt

Solution mining is an alternative to mechanical excavation of salt ores (Richner et al. 1992). Since most waste components in solution mining are not soluble they are left behind to settle to the bottom of the expanding cavern, as the brine product is removed to a surface processing facility. Unlike conventional mining, there are no large above
