Construction and application of "eight in one" closed-loop management and control mode of roof water disaster in coal mines

The prevention and control of coal mine water disaster is one of the key points of mine safety control, but the lack of comprehensive, systemetic, controllable technology management restricts the safe and efficient mining of coal resources. To guide the prevention and control of coal mine water disaster in a scientific and effective approach, taking the water disaster of coal mine roof as an example, using the theoretical system of system engineering and closed-loop management, this paper proposes a closed-loop management and control mode of roof water disasters, including stereoscopic probe, prediction, tracking exploration and discharge, subsection drainage, pre-mining evaluation, step drainage, monitoring and early warning, summary and optimization. The mode covers the management and control of the whole process of hydrogeological condition exploration, water disaster prediction, roof water drainage, as well as water disaster monitoring and early-warning, and forms a feedback path from the water disaster control effect to each stage of the water disaster prevention and control process. That means a closed loop of water disaster prevention and control was formed, which ensures that the water prevention and control work has scientific basis and can be regulated. This mode can be applied to roof water management and control under deep and complicated hydrogeological conditions, realizing the collaborative innovation of water control technology and management philosophy. It ensures the safe and efficient coal mining and provides reference for the roof water disaster management and control of coal mining under deep and complicated hydrogeological conditions.
