Abstract
In order to study the development law of water conduction overburden fracture zone in shallow coal seam mining in Miaohagu mining area,taking No.133103 Face of Anshan Mine as the research background,the development law of overburden fracture after No.3-1 coal seam mining was studied by means of theoretical analysis and field measurement.The results showed that the caving zone height of No.133103 Face was 10.69～15.88 m,the caving ratio was 4.86～5.73,the development range of water conduction fracture zone was 52.33～62.52 m,and the cracking ratio was 23.8～28.4.The research results provided a reference for the prevention and control of roof water disasters in working face mining under similar conditions in Miaohagu mining area.关键词
