Description
Technical field
The present invention relates to the method for coal mine drainage water in gob area, be specially roadway tiretube process discharge water in gob area method.
Background technology
Because coalfield, top resource is petered out, association and what come is that water in gob area is on the increase, under cover safely mining of coalbed and form hidden trouble, detection and exploitation bottom resource and to solve the problem of top water in gob area extremely urgent.
At present, in field, colliery, the world, known discharge water in gob area method beats big diameter borehole on ground, the bore of these borings is general all at more than diameter 450mm, and need before construction big diameter borehole to bore the detection of small-bore water exploring drill hole, then water in gob area be pumped to ground with water pump or discharged by down-hole by assigned address drilling a certain in down-hole, to reach the object of discharge Overburden gob area ponding; Said method is time-consuming, effort, cost are higher.
Summary of the invention
The present invention is time-consuming in order to the method solving existing discharge water in gob area exists, effort, problem that cost is high, provide roadway tiretube process discharge water in gob area method, the method is applied for many years at Datong Coal Group Company, and achieves good economic results in society.
The present invention adopts following technical scheme to realize: roadway tiretube process discharge water in gob area method, comprises the following steps:
At surface drilling until communicate with goaf, then by the electrical measuring method determination gob floor degree of depth and water in gob area water level;
In boring, put into the diameter coordinated with borehole standoff of setting female water pipe to connect into by two ends as first sleeve pipe of Ф 1, the bottom end seal of the first sleeve pipe withstands gob floor, is provided with externally threaded tube connector connects between water pipe with two ends;
Along the boring that the diameter first set pipe bit diameter that is Ф 1 is Ф 2, until during 10-15 rice position, distance objective tunnel, drill diameter be the boring of Ф 3 until communicate with target tunnel, and Ф 1 > Ф 2 > Ф 3;
The second sleeve pipe coordinated as the borehole standoff of Ф 2 with diameter setting female water pipe to connect into by two ends is put in the boring of diameter to be first sleeve pipe of Ф 1 and diameter be Ф 2, be provided with externally threaded tube connector with two ends between water pipe to connect, the body tube wall being positioned at goaf of the second sleeve pipe has drain hole, in the boring that diameter is Ф 3, places the 3rd sleeve pipe (the second sleeve pipe is connected with the effective reducer union of the 3rd cover) coordinated with borehole standoff;
The top end of the 3rd sleeve pipe is also placed with and can seals with port, top the sealing block contacted, and the bottom of the 3rd sleeve pipe is connected with the gutter in target tunnel;
When discharging water, successively mention the first sleeve pipe and sealing block, the ponding in goaf flows into the second sleeve pipe and the 3rd sleeve pipe in the drain hole of the second sleeve pipe, finally by the gutter in target tunnel by down-hole discharged to ground.
The boring that the present invention bores on the ground can detect the water accumulation level in goaf, reasonably can carry out the discharge of water in gob area; The boring reducing place of to be the boring of Ф 2 and diameter the be Ф 3 of the diameter especially in this method hangs and is provided with sealing block, controls, ensure the safety of draining for draining.
The present invention can while detection water in gob area, simply, to drain effectively, safely the ponding in goaf, the present invention also can utilize water exploring drill hole, existing ground to discharge, do not need to beat big diameter borehole on ground and can discharge water in gob area, this method duration is short, cost is low, provide powerful support for for Safety of Coal Mine Production provides, not only can discharge individual layer water in gob area, and multilayer water in gob area can be discharged.

Detailed description of the invention
Roadway tiretube process discharge water in gob area method, comprises the following steps:
Ground drill diameter be the boring of 133mm until communicate with goaf, then determine the goaf roadway floor degree of depth and water in gob area water level by electrical measuring method;
In boring, put into the diameter setting female water pipe to connect into by two ends withstand goaf roadway floor as the bottom end seal of first sleeve pipe 1, first sleeve pipe 1 of 127mm, be provided with externally threaded tube connector with two ends between water pipe and connect;
Be the boring of 113mm along the first sleeve pipe 1 drill diameter, until during 10-15 rice position, distance objective tunnel, drill diameter is that the boring of 93mm is until communicate with target tunnel;
The diameter of setting female water pipe to connect into by two ends the second sleeve pipe 2 as 108mm is put in the boring that the first sleeve pipe 1 and diameter are 113mm, be provided with externally threaded tube connector with two ends between water pipe to connect, the body tube wall being positioned at goaf of the second sleeve pipe 2 has drain hole 5, in the boring that diameter is 93mm, is placed with the 3rd sleeve pipe 3 that diameter is 89mm;
The top end of the 3rd sleeve pipe is also placed with energy and is connected with the gutter in target tunnel with the bottom that port, top seals sealing block the 4, three sleeve pipe contacted;
Successively mention the first sleeve pipe and sealing block, the ponding in goaf flows into the second sleeve pipe and the 3rd sleeve pipe in the drain hole 5 of the second sleeve pipe, discharges finally by the gutter in target tunnel.
