Exploitation Contradictions Concerning Multi-Energy Resources among Coal, Gas, Oil, and Uranium: A Case Study in the Ordos Basin (Western North China Craton and Southern Side of Yinshan Mountains)

Abstract: Abstract:The particular "rich coal, meager oil, and deficient gas" energy structure of China determines its high degree of dependence on coal resources. After over 100 years of high-intensity mining activities in Northeast China, East Region, and the Southern Region, coal mining in these areas is facing a series of serious problems, which force China's energy exploitation map to be rewritten. New energy bases will move to the western and northern regions in the next few years. However, overlapping phenomena of… Show more

“…In general, the height of the WFFZ is 9-12 times the mining thickness for weak strata, 12-18 times the mining thickness for medium-hard strata and 18-28 times the mining thickness for hard strata. Through theoretical analyses and field [19]).…”

“…The advanced distance ( ) is defined as the horizontal distance between the working face and the point where the surface begins to move (with a surface subsidence of 10 mm). The angle of advanced influence (δ, also known as the major influence angle) is related to the advanced distance and mining depth (ℎ), and their relationship is as follows [18]: [19]).…”

“…In the process of mining activities, the equilibrium state of the original rock stress in the overburden strata is destroyed, which leads to collapse, fracture and bending in the mining overburden strata. Once these fractures are interconnected with a water-bearing body (surface water, goaf water or aquifer water) in the mining overburden strata, the mine water will flow into the working face and bring huge economic losses and casualties, as illustrated in Figure 1 [4]. With the increase of mining depths, mining intensity and mining speed, the problem of mine water is becoming more prominent [5].…”
