ANALYSIS OF THE KARST DEVELOPMENT LAW BASED ON MULTIPLE EXPLORATION TECHNOLOGIES OF CAMBRIAN LIMESTONE

Öz

Coal mine floor limestone aquifers are a major source of water inrush from the coal seam floor and a serious threat to the safety of coal mining. In order to
reduce and avoid the occurrence of water inrush within the coal mine, we use multiple detection techniques, which are geophysical exploration technology,
drilling technology, water inrush accidents and tracer test, to develop a multi-faceted exploration of karst development and analyze its development
characteristics in the Chaochuan mine No. 1 well. The results show that, the Cambrian limestone (CL) karst water is poor; there is a certain hydraulic
connection. Near faults F5, F1, F125, and SF28, the area is less water-rich area, and the deep karst water forms a closed area; 61.54 % of shallow water inrush
accidents in the Taiyuan limestone and CL karsts were caused by large tectonic and nearby shallow faults. The karst vertical zonation is shallow; the shallow
water level decreased more in the West Wing of the No. 1 well than in the East Wing.
