Description

Technical Field

[0002] Advanced water detection and release devices are used in underground engineering projects such as mines to detect and release groundwater in advance to ensure construction safety. They organically combine drilling and geophysical exploration technologies, equipping the borehole with a special probe and propulsion device. Utilizing technologies such as borehole polarization, borehole electromagnetic tomography, and borehole radar, they can conduct inexpensive, short-range, and precise geophysical exploration in a limited number of boreholes. They can detect the water content of the strata within a certain range around the borehole and at the bottom of the borehole, and automatically analyze and interpret the detection data.

[0003] In existing coal mine working faces, when drilling through water layers during advance water exploration and drainage, the released water contains a large amount of impurities. There is a lack of effective purification and circulation methods, which leads to the waste of water resources and increases drainage costs. At the same time, during the use of drilling equipment, uneven terrain makes it difficult to support the equipment stably, affecting the accuracy and effect of water exploration and drainage. To address this, we propose an advance water exploration and drainage device for coal mine working faces. Utility Model Content
