Accompanying drawing explanation
Fig. 1 is the location determining method schematic diagram of open coal mine underground reservoir of the present invention;
Fig. 2 utilizes the groundwater reservoir position of the location determining method of open coal mine underground reservoir of the present invention to determine schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, a preferred embodiment of the present invention is described in detail.
As shown in Figure 1, the invention provides a kind of location determining method of open coal mine underground reservoir, comprise the steps:
Step is 1.: the tectonic structure of exploration open coal mine exploiting field bottom section, gathers the rock specimens of institute's survey area bottom open coal mine exploiting field simultaneously.
As a preferred embodiment of the present invention, described exploration is geophysical survey and/or prospecting by boring, and the present invention is preferably from being positioned at the dark station acquisition rock specimens of 10m bottom open coal mine exploiting field.Certainly, the present invention can also know the tectonic structure in described exploiting field further combined with the hydrogeological data coal rock layer survey data in described open coal mine exploiting field.
Step is 2.: the tectonic structure judging institute's survey area, select the rock specimens of the survey area of geology construction of stable to carry out osmotic coefficient investigating, the present invention can be measured by the infiltration coefficient to described rock specimens by hydrostatic head method test method(s) or varying head test method(s).
As a preferred embodiment of the present invention, the stable survey area of described tectonic structure can comprise horizontal tectonics and/or oblique structure, but cannot comprise the survey area of the tectonic structure instability such as fracture, tomography, staggered floor.The infiltration coefficient selecting the survey area of geology construction of stable to measure rock specimens is because the barrier performance of the tectonic structure self of some instability is poor, affect the storage capacity of the groundwater reservoir built on this basis, such as build groundwater reservoir in the position do not planned a successor, the water body in reservoir can penetrate into darker underground from position of fault.
Step is 3.: selected area update strategy coefficient is less than or equal to the survey area of predetermined value as candidate area, measures the distance in described candidate area and next exploiting field.
Predetermined value in abovementioned steps is preferably 1.0 × 10
-6cm/s, selected area update strategy coefficient of the present invention is less than or equal to 1.0 × 10
-7the region of cm/s as candidate area to guarantee that open coal mine underground reservoir yet to be built has better barrier performance, to improve its water storage performance further.If the tectonic structure of survey area infiltration coefficient that is unstable or survey area is all greater than 1.0 × 10
-6cm/s, the present invention can also carry out reinforcement seepage control project at corresponding open coal mine exploiting field bottom section, such as, lay impervious barrier.Certainly, the present invention can also select other predetermined values be applicable to ensure the barrier performance of groundwater reservoir according to the practical factor such as water quality and geologic condition.
Step is 4.: select candidate area minimum with the distance in next exploiting field in all candidate area as the installation location of open coal mine underground reservoir, such as, and the candidate area that the edge in next exploiting field of chosen distance is minimum.Make candidate area and next exploiting field keep the object of less distance be convenient water body of carry in the open coal mine underground reservoir of building, reduce energy consumption, cost is carried in saving.Similarly, in order to fully utilize surface water, the present invention preferably can also measure the distance sum of described candidate area apart from next exploiting field and surface water, and the minimum candidate area of chosen distance sum is as the installation location of sky coal mine underground reservoir.
More preferably, the gravel that the present invention utilizes the current exploiting field of exploitation to peel off and sandy gravel are to backfill open coal mine underground reservoir, therefore in order to reduce the cost of transport backfill, the present invention can also measure described candidate area apart from next exploiting field, the distance sum of the refuse dump in surface water and current exploiting field, the minimum candidate area of chosen distance sum is as the installation location of sky coal mine underground reservoir.Similarly, the present invention can also select according to actual environment the position being applicable to construction open coal mine underground reservoir, the factors such as such as surface buildings.
As shown in Figure 2, be further described for the addressing of Shenhua Group open coal mine underground reservoir, this open coal mine is divided into five exploiting fields: the first exploiting field 2, exploiting field 1, second, the 3rd exploiting field 3, the 4th exploiting field 4 and the 5th exploiting field 5, current first exploiting field 1 has been exploited complete, exploitation work is advanced into the second exploiting field 2, carrying out the stripping operation in the second exploiting field 2 at present, therefore bottom the first exploiting field 1, carrying out groundwater reservoir position and determine.
Step is 1.: utilize geophysical survey and prospecting by boring mode to explore the tectonic structure of the coal mining hole bottom section in the first exploiting field 1, gather the rock specimens of 10m depths bottom institute's survey area simultaneously.
Step is 2.: analyze the stratum of hole bottom section of mining, rock stratum, structure and judge, the rock specimens of the survey area of geology construction of stable is selected to carry out osmotic coefficient investigating, as shown in Figure 2, select the coal mining hole of bottom geology construction of stable, namely filter out region A, B, C, D that tectonic structure is horizontal tectonics or oblique structure.
Step is 3.: measure the infiltration coefficient of region A, B, C, D, and the infiltration coefficient of described exploration A, B, C, D is all less than or equal to 1.0 × 10
-6cm/s, meet the requirement of open coal mine underground reservoir to bottom of the reservior, therefore region A, B, C, D all can be used as candidate area.
Step is 4.: the minimum region A of the distance in selected zone A, B, C, D and lower second exploiting field 2 is as the installation location of open coal mine underground reservoir.As shown in Figure 2, region A is nearest apart from the second exploiting field 2, therefore builds open coal mine underground reservoir at this place.By the open coal mine underground reservoir that said method is determined, both in convenient conveying water body to described open coal mine underground reservoir, can also energy consumption be reduced, save conveying cost.In addition, the distance sum of region A distance surface water position and refuse dump is minimum, therefore set up open coal mine underground reservoir at A place and not only by groundwater reservoir and ground statement comprehensive utilization, can also reduce the transportation cost backfill on refuse dump being transported to region A.
Above-described embodiment is used for illustrative purposes only; and be not limitation of the present invention; the those of ordinary skill of relevant technical field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all equivalent technical schemes also should belong to category of the present invention, and scope of patent protection of the present invention should be limited by each claim.
