Abstract
To underground space, particularly the mining area is carried out the method for draining, the method is with manual method the storage area to be carried out draining or compiled percolating water, and by means of the underground water pumping plant with by at least one filling port water is injected water-filling and press, be separated with impervious break between the water-filling district and the underground space, and it is characterized in that: water is directly injected the water-filling district and will not rise on the ground by water from the underground space, used pressure then is lower than the water-resisting ability between storage area and the water-filling district during water filling, and the while is less than the minimum rock intensity of impervious break between the underground space and the water-filling district.
Description
The present invention relates to the artificial drainage method in the underground space, particularly mining area, comprise and the water of storage area discharged or percolating water compiled and inject the water-filling district that separates by the impervious break and the underground space, comprise getting out at least one filling port, by with the underground water pumping plant water filling of described filling port to the water-filling district.
Draining the most frequently used method in mining area is that the water or the percolating water of will discharge from the mining area compile, and with water pump it is risen on the ground.When the water in the stratum must be regulated owing to exploiting draining or natural drainage disequilibrium, the water (or the such water of part) that will elevate from the mining area through water injection well was drawn back underground storage area again usually.
Water is constantly discharged from the mining area and will be sent back from the water that extract out underground storage area again, and this dual technical purpose just can realize fully with existing method, but this method is too complicated and expensive.In addition, water is being refilled the danger that can strengthen contaminated environment in addition when underground from ground.
The objective of the invention is to eliminate above-mentioned shortcoming, just will provide a kind of and existing method to compare, expense is lower, is subjected to the dangerous less method of outside contamination, in order to water from the mining area with other underground spaces are discharged and it is sent back in the ground water regime go.
Essence spirit of the present invention is to recognize: if can satisfy following two conditions, just can make the water of discharging from underground storage area in order to protect the underground space or make percolating water turn back to underground water-filling district.First condition is: should have sufficiently high water-resisting ability between catchment in ground water regime and the water-filling district; Second condition is: should have impervious break between the water-filling district in mining area and ground water regime, wherein, making interlayer self that hydraulic pressure that spontaneous fluid power breaks take place should be greater than used water-filling pressure.
As not satisfying first condition, when water-filling, displacement or water percolating capacity all can sharply increase.
As not satisfying second condition, the water that pressurized returns in ground water regime will cause in impervious break that fluid power breaks, and when water-filling, the water in the underground water storage system will be poured into the mining area.
Therefore, the present invention from the underground space particularly from the method for mining area draining, comprise and the water of storage area discharged or percolating water compiled and inject the water-filling district that separates by the impervious break and the underground space, comprise and get out at least one filling port, by with the underground water pumping plant water filling of described filling port to the water-filling district, promptly under pressure, directly inject the water of discharging or collecting, make said water continue to stay below the stratum, ground from the underground space to the water-filling district.
Another characteristics of this method are: the hydraulic pressure that injects the water-filling district is less than the water-resisting ability between storage area and the water-filling district, and the while is less than the minimum rock intensity of the impervious break between the underground space and the water-filling district.
This method also can be carried out explosion and measure burst pressure impervious break, and adopts than burst pressure at least 5%, and the pressure of preferably little 10-15% injects the water-filling district with water.
Under certain conditions, this method also can adopt known output increase method (as acid treatment) and (or) to the filling port carry out explosion with explosion with attenuating water-filling pressure.
Another kind of feasible effective ways are by at least one pack hole, and filler or the casting resin that contains cement are filled between storage area and the water-filling district.
Under other possible situation, this method can also be with its purification before percolating water injects the water-filling district.
In the enforcement of this method, preferably will be the percolating water of part or the water that part is discharged from the storage area at least, by means of filter well, with a kind of known method that ensures mining operations, collect in a sealing or at least can antipollution gravity collecting loop in, again its guiding is installed in the water-filling pump works in the mining area.
By means of the water-filling pump works, in case of necessity after treatment, water is injected in the water storage section via the filling port, between the catchment of this section one underground water storage system, be separated with the zone of a high water resistant ability, and between this section and mining area, being separated with an impervious break, this impervious break has the anti-fluid power rupture strength greater than water-filling pressure.
In underground storage area owing to the reason on the geological structure or owing to existing impervious break and be subjected to cutting off, can carry out suitable selection to the storage area, just can between catchment and water-filling district, obtain enough big water-resisting ability, and in other situations, measure then at least should be partly carried out filling to the energy circuit of water as a supplement, to increase the water-resisting ability between catchment and the water-filling district.
Produce the reliability that fluid power breaks between the water-filling district in the storage area and should carry out two kinds of detections for preventing in mining area or other underground spaces and being located at, that is: impervious break is carried out tentative explosion and make pressure detecting and the storage area is carried out experimental water-filling and made pressure detecting.
According to the data that record, should make it suitable increase by the following method for worst minimum breaking resistance: the distance between selected water-filling district and the mining area, make it reach the limit that meets under the virgin stress condition at the most, and (perhaps) reduces required water-filling pressure by following manner, promptly want the end to increase the quantity of filling port, lastly adopt known output to increase method (as acid treatment) or explosion is carried out in the filling port.
Also might obtain can be for the very favourable storage area of water-filling, and hydraulic pressure wherein can needn't be finished water-filling by water sorption by pumping.
The present invention can describe in conjunction with following example.
Fig. 1 shows an example of the method for understanding the present invention, and hydrogeological environment wherein is: have water route far away between draining stratum and the water-filling stratum and connect;
The situation of application examples shown in Figure 2 is: catchment and water-filling district be with from same storage area, but since the geology staggered floor, no direct water route connection between catchment and the water-filling district;
Example shown in Figure 3 relates to such situation: the water route between catchment and the water-filling district connects by the part filling being carried out in the water route and being weakened to some extent;
Situation shown in Figure 4 is: because scarce capacity, or for reduce simultaneously the fortune water rate with and alleviate from underground storage area draining unfavorable factor economically, promote the water yield and seek from the mining area of having exploited, to reduce.Another difference of comparing with above-mentioned each example is, the water that occurs in the mining area is infiltration and without drain hole, but also can use drain hole simultaneously.
As shown in Figure 1, the underground space 1 is arranged in ore bed 22, is storage area 2 on the underground space 1, and the underground space 1 is jeopardized in storage area 2.Unconformable stratum is passed in storage area 2, exists the water route in the water-filling district 3 of place below the underground space 1 away from ore bed 22 and is connected, and is separated with impervious break 4 between the water-filling district 3 and the underground space 1.Carry out draining with the protection underground space 1 by the 8 pairs of storage areas of drain hole 2 that originate in the underground space 1.In drainage procedure, the initial water level 24 of storage area 2 promptly becomes decline water level 11.Before water-filling,, the water of discharging is risen on the ground by fortune water pipe 18 by means of safe water pumping plant 17.Before the beginning water-filling, should in explosion injection orifice 9, measure the pressure P r that impervious break 4 is broken, this explosion injection orifice 9 is positioned near the impervious break 4 predetermined injection positions, the nearside in water-filling district 3.Explosion injection orifice 9 usefulness after-hardening materials should be blocked then.After this, should in the experimental water-filling hole 10 in water-filling district 3, carry out water injection test, experimental water-filling hole 10 is to be provided with on the basis of explosion bulge test in early stage, the used pressure of water injection test should not surpass the 85-90% of fracture pressure Pr, and the purpose of water injection test is to determine by means of charging pump 12 by the water yield that the filling port can be injected.As addition thereto, also can adopt output to increase method as the volume increase blasting procedure.After the water yield that determines displacement and can inject, just should expand to simultaneously in the system of whole drain hole 8 and filling port 5 and go by filling port.Should go guiding in the filling port 5 by pipeline 13 and charging pump 12 through the water of sedimentation in the drain hole 8.Should dispose a general reducing valve to each filling port 5, for example dispose a bleed valve, water-filling pressure is transferred to 90% of fracture pressure Pr.
By above measure, changed the preceding water level 14 of water-filling district 3 water fillings, thereby made the pressure of the water level 15 after the raising be lower than the pressure P r that can cause impervious break 4 to break all the time.
From in the water of drain hole 8 not the part of sedimentation then pass through by means of safe water pumping plant 17
