Embodiment

[0043] Select the location of the underground reservoir in a coal mine area.

[0044] Such as figure 2 As shown, taking the site selection of a coal mine underground reservoir as an example for further explanation, the coal mine is divided into five mining areas: the first mining area 1, the second mining area 2, the third mining area 3, the fourth mining area 4 and the In the fifth mining area 5, the mining of the first mining area 1 has been completed, and the mining of the second mining area 2 is currently underway, so the location of the underground reservoir is determined at the bottom of the first mining area 1.

[0045] Step ①: Utilize geophysical exploration and drilling exploration technology to explore the geological structure of the overlying strata in the first mining area 1, and at the same time collect rock samples of the surrounding rock of the coal mine in the exploration area.

[0046] Step ②: Analyze and judge the strata, rock formations, and structures of ...

Abstract

The invention relates to a coal mine underground reservoir position selection method based on water resource transferring paths. The method comprises the steps that a geologic structure is explored before coal mine exploiting; according to the geologic structure, areas with stable geologic structures are taken as alternative areas; water diversion fissure zone heights of various alternative areasare calculated, and the alternative areas with the water diversion fissure zones reaching overlying water-bearing rock stratums after stable exploiting are taken as new alternative areas; judgement and flow distribution statistics are carried out on the water resource transferring paths, and the alternative areas with flow greater than preset flow are selected as new alternative areas; disintegration resistance indexes of rock samples and permeability coefficients of fractured rock masses in the new alternative areas are measured, and the alternative area with the disintegration resistance index greater than or equal to a preset disintegration resistance index value and the permeability coefficient less than or equal to a preset permeability coefficient value is selected as a constructionposition of a coal mine underground reservoir; the coal mine is exploited, and the coal mine underground reservoir is constructed.

Description

technical field [0001] The invention relates to the technical field of location selection of underground water reservoirs, in particular to a location selection method for underground water reservoirs in coal mines based on water resource transfer paths. Background technique [0002] The five provinces of Inner Mongolia, Shanxi, Shaanxi, Xinjiang, and Ningxia accounted for 73.8% of the national raw coal output in 2017 (according to the National Bureau of Statistics), and the identified coal resource reserves accounted for about 80% of the national total reserves. However, this region is located in my country's arid-water-scarce zone and semi-arid-water-scarce zone, and its water resources only account for 5.96% of my country's (according to the data in the 2017 China Statistical Yearbook). Water resources are the dominant factor affecting coal mining and ensuring ecological security in this region factors, and play the role of basic configuration. [0003] Large-scale and hi...
