Water control method for abnormal water-enriched region of coal mine

Abstract

The invention discloses a water control method for an abnormal water-enriched region of a coal mine. The water control method is a comprehensive water control technology which takes a water pressure and water quality monitoring network, a borehole imaging technology, a comprehensive detecting technology for underground water yield property and a sandstone water controlling and dredging technology as cores and has functions of underground exploration environment detection and control. The water control method makes up the blank in the field, creates a precedent for an underground comprehensive exploration and control technology, is remarkable in economic benefit and capable of ensuring the safe production of the coal mine and provides the technical support and excellent reference experience for the underground water control work of the same kind of coal mines.

Description

technical field [0001] The invention relates to the field of coal mine exploration and water prevention. Background technique [0002] At present, when some mines near rivers and lakes (such as the Yellow River North Coalfield) are mined, due to the low degree of exploration, the existing geological data cannot meet the needs of water prevention and control in the underground water-rich anomaly area. In order to prevent water damage, supplementary exploration is required. Due to the limitation of the ground layout drilling rig conditions by various factors, it is impossible to carry out supplementary exploration on the surface. Affected by geological and hydrological conditions, groundwater is often buried in wells in abnormally rich water areas, which poses a threat to mine mining. After the groundwater situation is verified, certain measures need to be taken to prevent and control it. complete set of technologies for water disaster detection and prevention. Contents of...
