Description

Technical Field

[0001] This utility model belongs to the field of drilling technology, specifically relating to a drilling device for water control in coal mines. Background Technology

[0002] During coal mine construction, atmospheric precipitation, surface water, and groundwater enter the mine through various channels, flooding underground roadways, working faces, and chambers, affecting normal mine and working face production, and causing casualties. These accidents are called water inrush accidents. Therefore, it is crucial to conduct thorough mine water exploration and drainage work. For mines where working faces are affected by water hazards, a water inrush condition analysis must be carried out, adhering to the principles of prediction and forecasting, investigation in case of doubt, exploration before excavation, and treatment before mining. Mining activities are strictly prohibited in areas where the hydrogeological conditions within and around the coal mine are unclear, and mining beyond designated layers or boundaries is strictly prohibited. To ensure safe coal mine production, water exploration drilling rigs are often used to explore and drain potential water sources. This exploration and drainage process requires drilling equipment, which is a movable platform equipped with a drilling rig, to drill into the inner surface of the coal mine.

[0003] The outer frame of existing drilling equipment is often fixed, and the size of the entire equipment is not easy to adjust. This causes some inconvenience to the placement of the drilling equipment, especially in narrow mine tunnels, where it is very difficult to move large drilling equipment. Therefore, it is necessary to design a new drilling equipment to solve this problem. Utility Model Content
