Analysis of the karst development law based on multiple exploration technologies of Cambrian limestone

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