Study on Height of Water Conduction Fracture Zone of Full-mechanized Caving Face with Hard Roof

When the roof water-conducting fissure zone develops to the water body,the water body en⁃
ters the working face along the fissure,which seriously destroys the ecological environment of the mine and
affects the work safety and efficiency. Taking the 150105 working face of 15# coal seam in Panchengling Coal
Mine as the research object,the development height of the water-conducting fracture zone of 15# coal seam
is analyzed by empirical calculation formula,and the development height of the water-conducting fracture
zone of 15# coal seam is determined comprehensively by combining upward hole water injection leak detec⁃
tion method and borehole television imaging method. The results show that the maximum development height
of the water-conducting fracture zone is predicted to be 81.56 m by the empirical calculation formula,79.99
m by the upward hole water injection leak detection method,and 79.46 m by the borehole television imaging
method. Finally,the height calculated by the empirical formula is highly consistent with the field measured
results,which can provide guidance for water damage prevention and safety production of 15# coal seam in
Panchengling Coal Mine.
