Problems solved by technology

The above-mentioned prediction and forecasting systems for Austrian ash water outburst at home and abroad cannot meet the above requirements, so they are rarely used in production practice, resulting in frequent occurrence of water inrush accidents in mines, and there is no ideal technical plan for preventing and controlling Aoshan ash water outburst

Embodiment Construction

[0028] In order to further illustrate the technical scheme of the present invention, at first in conjunction with the attached figure 1 , 2 3. Describe in detail the principle of regional forecasting of Austrian gray water outburst. According to the prominent gestation process of Austrian Huishui, it is described in the following three situations.

[0029] 1. Structural (fault) belts and the situation when there is no carbon pillar and primary water conduction: (see figure 1 , 2 )

[0030] In the figure, 1 indicates the coal seam, 2 indicates the structural zone, 3 indicates the small aquifer near the coal seam, 4 indicates the small aquifer near the Austrian ash water layer, 5 indicates the Austrian ash water layer, 6 indicates the monitoring hole, and 7 indicates no carbon column.

[0031] In fact, the small aquifer 3 and the small aquifer 4 are always in communication with the Austrian limestone aquifer 5 through the primary water-conducting structural zone 2 or the car...

Abstract

A method for monitoring and forecasting the sudden flooding in mine includes such steps as searching a small water-bearing layer in the coal bed of Permo-Carboniferous period stratum for using it as monitor layer, locating the water level monitoring holes to form a monitor network, drilling each hole to said monitor layer, arranging the sleeve tube in each hole, installing water level sensors, pressure meters and data acquisition system, electrically connecting them to computer on the ground, and calculating and analyzing to obtain forecast information.

Description

Technical field: [0001] The invention belongs to the category of coal mine water hazards, and in particular relates to a method for preventing and controlling water inrush from aquifers of austrian limestone. Background technique: [0002] my country is rich in coal resources, which is an important part of energy composition. However, limestone karst is widely distributed in my country. With the depletion of shallow coal seams and the increase of mining intensity, the depth of mines continues to extend. Confined water from Ordovician limestone at the bottom of coal seams (abbreviated as Austrian gray water) is becoming more and more harmful, and mine water inrush accidents occur from time to time. Ordovician limestone outburst means that during the coal mining process, the Ordovician limestone karst confined water hidden under the coal seam floor suddenly pours into the mining area in large quantities along the fissure zone and structural zone (fault, carbon-free pillar) of t...
