The specific embodiment:
Below in conjunction with accompanying drawing and preferred embodiment, to the ore deposit, karst of foundation the present invention proposition
Exploratory shaft sinking water method for fetching water and the equipment specific embodiment, structure, feature and effect thereof, describe in detail as after.
Referring to Fig. 1-4, a kind of karst water prospection of mine method for fetching water, earlier to geological tectonic conditions in the scope of mining area, the karst developmental state, analyze mining area hydrostatic bit line, other hydrogeological conditions of the moisture situation of Mao Kou group (P1m) limestone is carried out comprehensive analysis, sum up this area maokou limestone water tax and deposit rule, by judging definite position, aquifer after the above condition research, determine that this water intaking boring design water intaking layer position is Mao Kou group (P1m) limestone, this layer carbonate containing rock karst water, watery is strong, by analysis, in this aquifer water intaking, water yield abundance, and it is stable, can satisfy mine production, living water use, determine further research method for fetching water of back in the water intaking position, the design bore size, comprise the azimuth, the inclination angle, the degree of depth, aperture and aperture structure, be lower than the hydrostatic level absolute altitude+the 1000m level holes, it is the position of ZK2 number boring among Fig. 2, the ZK1 drill center is apart from ZK2 drill center 0.5m, and close to the aquifer, water can flow out boring automatically after water was found in boring herein, utilize near the interim sump of boring as intermediate transit point, be promoted to the ground head-tank by pump.
Above-mentioned drilling construction can doublely be done maokou limestone strong aquifer water-level observation hole after finishing, and only needs to install pressure meter at aperture valve place and can observe its water pressure, determines its hydrology with this.
The used equipment of above-mentioned method is: boring 1 connects steel pipe A2, and steel pipe A2 goes up setting pressure table 3 and gate valve 4, and steel pipe A2 is connected to interim sump 5, and steel pipe B6 goes up water pump 7 is installed, and steel pipe B6 connects ground head-tank 8.
The present embodiment strata structure is packsand, 0.6 meter 12# coal seam, argillaceous siltstoue, 2.1 meters 13# coal seams, argillaceous siltstoue, limestone, 0.7 meter 14# coal seam, limestone, argillaceous siltstoue, limestone.
Mine their location general area geological structure all belongs to this kind geological structure band, common moisture characteristics are arranged, as long as after checking, in the enough same scheme constructions of other local energy equally water detection, certainly different local certain othernesses that have certainly, only need the concrete overall geological conditions of hydrogeological conditions calmodulin binding domain CaM is carried out binding analysis, determine that moisture abundant Mao Kou organizes the limestone position and can find the position, aquifer, can further implement water extracting scheme.
The construction of present embodiment boring shaft bottom signal chamber forward 30.5 meters right+chamber in left side, 1000 meters shaft stations in, the chamber orientation is 180 degree, 2 meters in the dark right group of concrete size, 0.1 meter in left side group, wide, height is respectively 1 meter, 1.6 meters stalk semicircular arches.
The present embodiment data of holes drilled is azimuth 180 degree, inclination angle 81 degree, and 68 meters of hole depths, aperture tertiary structure 127|93|75 millimeter, position of opening is at the chamber base plate.
Technological merit of the present invention:
(1) the present invention only needs in 2 water intaking borings of down-hole construction, and head-tank pipe laying circuit in down-hole to ground is short, safeguards easily simple; And position, shaft station, down-hole is positioned at below the hydrostatic level, can flow out certainly after finding water, is better than in other local punching.
(2) dry point and head-tank drop are 400m, because circuit is short, only need 75kw motor one-level to promote and can satisfy, and power of motor is little, and the power supply expense will significantly reduce, and meet very much the energy-saving and emission-reduction requirement.
(3) adopt one-level to promote, only need to be equipped with a full-time pump worker, the attendant does not need special configuration, has significantly reduced maintenance cost, and quality of water supply can access fine assurance.
(4) circuit is short, the discrepancy in elevation is little.The down-hole pipeline can adopt the left 4 cun steel pipes of former unit in charge of construction, the cover discharge pipe line that ground adopts former design to use, and it is less newly to lay line segments, only needs to install water pump in the down-hole and gate valve get final product, minimizing investment cost and installation period.
(5) construction of holing by the down-hole water intaking, drilling construction can doublely be done maokou limestone strong aquifer water-level observation hole after finishing, thereby will less or avoid the ground face length to see the construction of boring, and water intaking boring is easier to the water-level observation of maokou limestone strong aquifer, only need to install pressure meter at aperture valve place and can observe its water pressure, determine its water level with this.
(6) water can flow out boring automatically after water was found in boring, not be used in layout pumping equipment in the hole, only needed to utilize near the interim sump of boring to be promoted to the ground head-tank as intermediate transit point by pump, did not have big maintenance cost basically, and economic benefit is obvious.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, any technical solution of the present invention content that do not break away from,, all still belong in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does according to technical spirit of the present invention.
