Description

Intelligent monitoring control method for coal mine land survey control water Technical Field The invention relates to the technical field of coal mine prevention and control water, in particular to an intelligent monitoring and controlling method for coal mine land survey prevention and control water. Background Coal is taken as an important energy source in China and occupies a key position in industrial production and economic development. However, coal mining operations often face complex hydrogeological conditions, and mine water damage is always a major hidden danger threatening the safe production of coal mines. In the past decades, although the coal mine industry in China has made a certain progress in the water control technology, the traditional water control work for coal mine field measurement still has a plurality of problems. On the one hand, the scheduling and regulation of the drainage device are lack of intellectualization, when sudden water damage is faced, errors and delays are easy to occur in the process of manually judging the position of the water damage and starting the drainage device, so that the water damage cannot be controlled in time, meanwhile, the drainage device usually operates according to preset fixed parameters, after water burst is detected, operation is immediately carried out according to the preset drainage flow and duration, and the operation parameters of the drainage device cannot be dynamically adjusted according to the actual conditions of the water burst, such as the scale, the water pressure, the underground water level and the like. If the drainage parameter is too small, accumulated water cannot be timely discharged, water accumulation and flooding of a roadway can be possibly caused, and the damage of water damage is aggravated, and if the drainage parameter is too large, not only is excessive consumption of energy and extra abrasion of equipment caused, but also the operation cost of a coal mine can be increased. This lack of flexibility and intelligent control is difficult to adapt to complex and variable water damage scenes. On the other hand, current water control works severely lack real-time monitoring and evaluation mechanisms for drainage effects. The actual drainage flow of the drainage device, the change of the accumulated water level and the water quality condition cannot be mastered in real time, so that the drainage effect is not expected, or the drainage in partial areas is not timely, and effective countermeasures are difficult to discover and take in time. The reliability of water control operation is greatly weakened, and absolute safety guarantee cannot be provided for underground coal mine operation. In order to solve the above-mentioned defect, a technical scheme is provided. Disclosure of Invention The invention aims to provide an intelligent monitoring control method for ground measurement control water for a coal mine, which aims to solve the problems set forth in the background.

And step three, scheduling operation drainage devices, namely acquiring drainage devices which are positioned at two sides of each hydrologic disaster source area in the underground coal mine roadway and are closest to the hydrologic disaster source, marking the drainage devices as a left operation drainage device and a right operation drainage device of each hydrologic disaster source area in the underground coal mine roadway, and controlling the starting of the drainage devices. Step four, regulating and controlling the operation drainage device, namely acquiring control parameters of the control of the hydrologic disaster sources detected by the left operation drainage device and the right operation drainage device in the underground tunnel of the coal mine, wherein the control parameters comprise water burst flow, water pressure, water level and water speed, analyzing reference drai
