Abstract
The invention relates to a method for draining ponding in a goaf of a coal mine, in particular to a method for draining ponding in the goaf by a laneway casing pipe method. The method comprises the following steps: drilling a hole in the ground to a seam floor of the goaf, placing a first casing pipe in the drilled hole, drilling a hole with the diameter being Phi 2 along the first casing pipe until the hole is 10-15m away from a target laneway, drilling a hole with the diameter being Phi 3 until the hole is formed in the target laneway, placing a second casing pipe in the first casing pipe and the drilled hole with the diameter being the Phi 2, placing a third casing pipe in clearance fit with the drilled hole in the drilled hole with the diameter being Phi 3, placing a water stopping block at the top end of the third casing pipe, enabling the bottom end of the third casing pipe to be connected with a water draining pipe in the target laneway, lifting the first casing pipe and the water stopping block, enabling ponding in the goaf to flow into the second casing pipe and the third casing pipe from a water draining hole in the second casing pipe, and draining the ponding through the water draining pipe in the target laneway. The problems that an existing method for draining the ponding in the goaf of the coal mine wastes time and labor and is high in cost are solved.
Description
Technical field
The present invention relates to the method for discharge goaf, colliery ponding, be specially roadway tiretube process discharge goaf ponding method.
Background technology
Because coalfield, top resource is petered out, association and what come is that goaf ponding is on the increase, under cover safely mining of coalbed and form hidden trouble, survey and exploitation bottom resource and to solve the problem of goaf, top ponding extremely urgent.
At present, in field, colliery, the world, known discharge goaf ponding method is to beat big diameter borehole on ground, the bore of these borings is generally all more than diameter 450mm, and before construction big diameter borehole, need to bore small-bore water exploring drill hole and survey, then with water pump, goaf ponding is pumped to ground or by a certain assigned address drilling discharges by down-hole 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
In order to solve the method for existing discharge goaf ponding, there is time-consuming, effort, problem that cost is high in the present invention, roadway tiretube process discharge goaf ponding method is provided, the method is applied for many years at Datong Coal Group Company, and has obtained good economic results in society.
The present invention adopts following technical scheme to realize: roadway tiretube process discharge goaf ponding method, comprises the following steps:
At surface drilling, until communicate with goaf, then by electrical measuring method, determine the gob floor degree of depth and goaf water accumulation level;
In boring, putting into and establishing by two ends the diameter with boring matched in clearance that female water pipe connects into is the first sleeve pipe of Ф 1, and the bottom end seal of the first sleeve pipe is withstood gob floor, is provided with externally threaded tube connector connects between water pipe with two ends;
The first set pipe bit diameter that is Ф 1 along diameter is the boring of Ф 2, until during 10-15 rice position, distance objective tunnel, drill diameter is the boring of Ф 3 until communicate with target tunnel, and Ф 1 > Ф 2 > Ф 3;
In diameter is the first sleeve pipe of Ф 1 and boring that diameter is Ф 2, put into by two ends, establish that female water pipe connects into diameter be the second sleeve pipe of the boring matched in clearance of Ф 2, between water pipe, with two ends, being provided with externally threaded tube connector connects, on the body tube wall that is positioned at goaf of the second sleeve pipe, have drain hole, in diameter is the boring of Ф 3, place and the 3rd sleeve pipe (the second sleeve pipe and the effective reducer union of the 3rd cover are connected) of boring matched in clearance;
The top end of the 3rd sleeve pipe is also placed with the sealing piece that can contact with the sealing of port, top, and the bottom of the 3rd sleeve pipe is connected with the gutter in target tunnel;
While discharging water, successively mention the first sleeve pipe and sealing piece, 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 diameter that the present invention bores is on the ground the water accumulation level that the boring of Ф 1 can be surveyed goaf, can reasonably carry out the discharge of goaf ponding; Diameter in this method is that hang and be provided with sealing piece at the boring of Ф 2 and boring reducing place that diameter is Ф 3 especially, for draining, controls, and guarantees the safety of draining.
The present invention can be when surveying goaf ponding, drain simply, effectively, the safely ponding in goaf, the present invention also can utilize the discharge of water exploring drill hole, existing ground, need on ground, not beat big diameter borehole and can discharge goaf ponding, this method duration is short, cost is low, for Safety of Coal Mine Production provides, provide powerful support for, not only can discharge individual layer goaf ponding, and can discharge multilayer goaf ponding.

The specific embodiment
Roadway tiretube process discharge goaf ponding method, comprises the following steps:
The boring that is 133mm at ground drill diameter until communicate with goaf, is then determined the goaf roadway floor degree of depth and goaf water accumulation level by electrical measuring method;
In boring, put into the bottom end seal of establishing the first sleeve pipe 1, the first sleeve pipe 1 that diameter that female water pipe connects into is 127mm by two ends and withstand goaf roadway floor, between water pipe, with two ends, be provided with externally threaded tube connector and connect;
The boring that is 113mm along the first sleeve pipe 1 drill diameter, until during 10-15 rice position, distance objective tunnel, the boring that drill diameter is 93mm is until communicate with target tunnel;
In the boring that the first sleeve pipe 1 and diameter are 127mm, put into by two ends and establish the second sleeve pipe 2 that diameter that female water pipe connects into is 108mm, between water pipe, with two ends, being provided with externally threaded tube connector connects, on the body tube wall that is positioned at goaf of the second sleeve pipe 2, have drain hole 5, in the boring that is 93mm at diameter, being placed with diameter is the 3rd sleeve pipe 3 of 89mm;
The bottom that the top end of the 3rd sleeve pipe is also placed with sealing piece 4, the three sleeve pipes that can contact with the sealing of port, top is connected with the gutter in target tunnel;
