Embodiment Construction
[0034] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.
[0035] like figure 1 As shown, the present embodiment is a kind of downhole emergency water level monitoring system, including the monitor 1 placed in the well site, the control panel 2, the drawworks 3 wrapped around the cable 31, and the measuring probe 4 placed in the downhole; the measuring probe 4 passes through the cable 31 is connected to the control panel 2, and the monitor 1 is connected to the control panel 2. The depth of the water surface is judged by the picture taken by the camera of the measuring probe 2 and the change of the splashes on the water surface when the measuring probe 4 touches the water,...

The invention discloses a downhole emergency water level monitoring system comprising a monitoring device arranged at a well site, a control panel, a winch with a cable wound, a measuring probe arranged under the well, and a fish float depth measuring device. The measuring probe is connected to the control panel by a cable; the monitoring device is connected with the control panel; the fish floatdepth measuring device is arranged before the lens of the measuring probe and is connected to the measuring probe. In addition, the invention also provides a method using the system. The downhole emergency water level monitoring system has the following beneficial effects: the height of the water level can be detected in real time and the trend diagram of the water level with time is drawn; the water inrush amount of the mine is evaluated qualitatively and quantitatively; the water inrush condition of the mine and the rescue and water blocking effects of the mine are predicted in advance and thus the assistance is provided for arranging various work of the mine in advance; and the work efficiency and the continuity of monitoring are improved.
Description
technical field [0001] The invention relates to an underground coal mine water control system and method, in particular to an underground emergency water level monitoring system and method. Background technique [0002] The groundwater (pore water source, fissure water source, karst water source) and surface water source in the gaps of the ore body or surrounding rock gushes out under pressure, which is called gushing water. Large, violent, and sudden water gushes are called water inrush. It is extremely harmful. Water plugging refers to cutting off the water gushing down the well. In order to prevent flooding accidents affecting the whole mine caused by sudden water gushing during the mining process, waterproof gates and waterproof walls are usually set up on the suitable section where the roadway passes through a water-resistant layer with sufficient strength. [0003] On May 25, 2017, a water inrush accident occurred in the connection lane of the bottom pumping lane of...
