Abstract: The effective mining of triangle coal is an effective means to improve the comprehensive benefits of mines. Taking this
as a starting point, this paper explored the application of the one-time support reduction technology for mining triangle coal in
fully mechanized caving in the mine. Based on the actual engineering practice, on the basis of analyzing the design of the scheme,
this paper determined the suitable mining scheme through comparison analysis, and analyzed and summarized the effect of the
scheme application. It is hoped to provide reference for the development of similar projects in other mines.
