Abstract
The present invention is a kind of drill well water mixeding mining method of lyotropic salt class salt deposit mineral reserve.Use producing well is concentrated on the salt deposit fixed point and not dispersed placement on the face of salt deposit and be communicated with exploitation comprehensively fully and do not take Fen Jing, divide well group to cut apart exploitation or Xian Fenjing, the branch well group is cut apart the basic skills that exploitation just is communicated with then.Can save exploitation engineering greatly, reduce cost, raise the efficiency, improve recovery ratio, and to help saliferous be that many salt deposits merge exploitation and the exploitation inclination angle is big, the salt deposit of complex structure.Be applicable to exploitation halite layer, sylvite layer, trona and chuco etc.
Description
Technical field that the present invention belongs to:
The present invention is a kind of drill well water mixeding mining method of lyotropic salt class salt deposit mineral reserve, is that a kind of new salt deposit drilling well hydromining is communicated with water-soluble method.The present invention is applicable to exploitation halite layer, sylvite layer, trona and chuco etc.
Background of invention:
From the water-soluble mining codes of the various inorganic salt deposits of underground mining is very much popular now in the world.
The salt deposit mineral reserve drill well water mixeding mining method that now grows up in the world, a water-soluble method in molten chamber for the individual well exploitation, one is the water-soluble method of connection of the higher well group connection exploitation of efficient.
The water-soluble method of existing connection has following two problems:
(1) dispersed placement producing well on the face of salt deposit, exploitation engineering is too huge.
(2) salt deposit divides well group to cut apart exploitation, and being limited in scope of connecting dissolution can not be given full play to the positive role that is communicated with hydromining, stays between well group simultaneously and much do not adopt surplus ore deposit.
Goal of the invention:
In order to solve (1) (2) two problems in above-mentioned 3, the present invention has designed new salt deposit mineral reserve drill well water mixeding mining method, i.e. " drilling hydraulic mining fixed-point producing method for salt deposit ".
Summary of the invention and implementation method:
(1), finds out point at the bottom of the structure of salt deposit according to the salt deposit constructional drawing.
(2) select the salt of producing whole salt deposit from the salt deposit structure end.
(3) on salt deposit structure end point, set up the production base, producing well is concentrated on the production base.
(4) water injection well is arranged on the countertendency direction of salt inclination layer maximum of producing well.
(5) if the some of exploitation salt deposit, then point at the bottom of the structure of determining this a part of salt deposit on the salt deposit constructional drawing.Select by above-mentioned (3) at the end at part salt deposit structure and to set up the method for production base and centralized production well to produce the salt of whole part salt deposit.The arrangement method of water injection well is identical with above-mentioned (4).
Should be bottom line at the bottom of the structure of salt deposit partly, partly at the bottom of the structure of salt deposit point can determine on bottom line suitable a bit.
(6) also can set up the production base and producing well be concentrated on this base salt in arbitrary fixing the selecting of salt deposit with the updip salt deposit of producing this fixed point.The arrangement method of water injection well is identical with above-mentioned (4).
The invention advantage:
(1) the water-soluble method of existing connection, dispersed placement producing well on the face of salt deposit, exploitation engineering is too huge.
The present invention then production base on the salt deposit fixed point arranges less producing well.Arrange less water injection well in addition according to circumstances.So just simplified exploitation engineering greatly.
(2) the water-soluble method of existing connection divides well group to cut apart exploitation to salt deposit, stays between well group and does not much adopt surplus ore deposit, can not further improve recovery ratio.
The present invention then is to the comprehensive connecting dissolution of large tracts of land salt deposit, exploitation comprehensively, has further improved recovery ratio.What the degree that recovery ratio improves was high can approach 100%.
(3) the water-soluble method of existing connection at individual other mining area and little salt deposit, exploiting the comprehensive exploitation that has formed the large tracts of land salt deposit latter stage naturally, has reached high recovery ratio.But owing to used the method for dispersed placement producing well on the face of salt deposit, so still there is the too huge problem of exploitation engineering.
The present invention has not only reached high recovery rate, and has simplified exploitation engineering greatly again, then for killing two birds with one stone, makes the best of both worlds.
(4) the water-soluble method of existing connection divides well group to cut apart exploitation to salt deposit, and being limited in scope of connecting dissolution can not be given full play to the positive role that is communicated with hydromining.Even other last large tracts of land salt deposit mining area and little salt deposit of connection comprehensively of forming is naturally arranged, be dispersed placement producing well on the face of salt deposit only, Xian Fenjing, branch well group are cut apart exploitation and just are communicated with then, therefore also still do not give full play to the positive role that is communicated with hydromining.
The present invention carries out complete connected sum in whole recovery process from start to finish by comprehensive exploitation of putting the large tracts of land salt deposit, therefore fully connecting dissolution salt deposit and brought into play the positive role that is communicated with hydromining.Because the present invention has given full play to and has utilized the usefulness and the potentiality of underground connection hydromining, this just for improve production efficiency greatly and significantly reduce Ground Operation, ground surface works has been created condition.This point is cardinal principle of the present invention and basic advantage.
(5) the water-soluble method of existing connection, the orientation of water injection well are not certain, are as the criterion with the producing well pressure burst communicatin being easy to, and tend to be arranged in the salt deposit of producing well more and walk upwards.
Water injection well of the present invention not only helps with producing well molten logically on the salt deposit countertendency direction of producing well, and helps in the underground hydromining fresh water and the differentiation of bittern and the underground scope that is communicated with of expansion rapidly, and production effect is fabulous.
(6) the water-soluble method of existing connection because being limited in scope of underground connecting dissolution is unfavorable for that interlayer is communicated with, so saliferous to be that many salt deposits separate zone production level is divided thinner, more, the exploitation engineering amount is also just corresponding more certainly.
The present invention helps linking up interlayer and is communicated with then owing to very big in the scope of underground connecting dissolution, can be that the division of many salt deposits separate zone production level is bigger, less to saliferous, merges exploitation to enlarge many salt deposits, and minimizing exploitation engineering amount improves production efficiency.
(7) the water-soluble method of existing connection is limited to and is applied to exploitation mild, the simply constructed salt deposit that tilts.If it is the salt inclination layer is bigger, just very unfavorable to exploitation.If the salt inclination layer is big, complex structure does not just have extraction value.
The present invention then utilizes salt deposit structural deformation condition consciously, with performance with utilize moving both vertically of underground hydromining, not only can exploit mild, the simply constructed salt deposit that tilts better, and helps more exploiting that the inclination angle is big, the salt deposit of complex structure.
