Mathematical Analysis of Factors Influencing the Development of Mining-Induced Fractures around Blind-Ended Openings with Particular Reference to Leichhardt Colliery

摘要

A general mathematical analysis is presented dealing with the development of mining induced fracturing around the blind ends of underground openings. Results of this general analysis are compared with specific observations of mining induced fracturing occurring at the Leichhardt Colliery of Queensland Coal Mining Co., Ltd., Blackwater, Queensland.
