Water disaster investigation and control in coal mine of Southern China

Abstract

The number of coal mines in Southern China was the possession of more than 60% of the total coal. This area was a large undulating terrain, and the terrain was so complex that the exploration was very difficult. The water damage had a great effect on southern mines. They were mainly threatened by the karst water and the goaf water. This thesis studied by mining geophysics and its methods, which were able to fit the characteristics of karst regions. Use those methods, we could detected and determined the location, size, distribution, and water-filled situation of geological anomalies that was closely related to mineral water disasters. Based on the characteristics of the mine on geology, water damage, mine drainage, this thesis studied the prevention and control measures for coal mine features in southern China to carry out scientific governing for mine water damage.
