The height of water-conducting fracture zone (HWCFZ) is one of the important technical parameters for water-preserved coal mining. The purpose of this paper is to acquire information about the height development characteristics of water-conducting fr
The height of water flowing fractured zone is a key parameter to implement water-retaining mining technology. In order to study the development height of water flowing fractured zone in shallow thick coal seam mining in ecologically fragile areas of
