Calculation Methods and Parameters Analysis of Mining Failure Depth of Coal Mining Face

Abstract

The research on the mining failure depth of coal seam floor is of great significance for the prevention and control of floor water and gas extraction. It is an extremely important part of coal mining process and has always been a key issue for scholars engaged in mining industry research. On the basis of referring to a large number of previous research results, this paper summarizes the calculation methods of floor failure depth caused by coal seam mining, introduces the theoretical methods commonly used for floor mining failure depth at home and abroad, and analyses the sensitivity of its parameters, aims to provide some references for relevant research.
