Discussions on Some Security Mining Problems of Fully-Mechanized Top Coal Mining in “Three Soft” Large Inclined Angle Working Face

This paper studies insecure factors of fully-mechanized top coal mining in “three soft” large inclined angle working face, which have impacted the normal generation badly, including rib spalling, roof fall and equipment slide, etc. Based on engineering practice of Du-Jiacun 1201 working face, the th...

Summary:This paper studies insecure factors of fully-mechanized top coal mining in “three soft” large inclined angle working face, which have impacted the normal generation badly, including rib spalling, roof fall and equipment slide, etc. Based on engineering practice of Du-Jiacun 1201 working face, the theory model of coal wall and supports force are analyzed, and protective measures are also put forward. Findings of the study provide technical support for coal mining efficiently and securely, and reference for the similar geological conditions.
