Prevention and control techniques & methods for water disasters at coal mines in China

Abstract

The prevention and control techniques and methods for mine water disasters classified with respect to water source，distribution relationship between mineral body and aquifer，water passage，et al，are presented.First of all，some key prevention and control techniques and methods for mine water disasters with water sources including precipitation，surface water，ground water，gob area water，recharged water from other aquifers and roof bed separation water are presented.Secondly，some key prevention and control techniques and methods for mine water disasters with different spatial distribution relationships between the mineral body and the aquifer including the water from the roof aquifers，the floor aquifers and the peripheral aquifers are presented.Finally，some key prevention and control techniques and methods for mine water disasters with different water passages including the karst collapse column，faults and cracks，narrow belt shape sub outcrop，et al，are presented.
