Study on Optimization of Fully Mechanized Working Face Arrangement Under the Influence of Geological Structure in Shallow Coal Seam
Fold structure and fault exist in fully mechanized mining face of 2-2 seam in Buertai coal mine.The faults encountered in 22101 and 22102 face are many and complex,the density of fault structure is high,and the inclined angle with the working face is between 50°and 60°.During the mining process,the two sides of the roadway are deformed greatly by the influence of geological conditions,and the phenomenon of roof and floor breaking is very serious.Combined with the above problems,this paper analyzes the rationality of length design of 2-2 coal seam working face.The length parameters of the working face are calculated by fitting the control theory of the rock stratum and the measured data,and the following conclusions are obtained.The reasonable working face length of 2-2 coal seam in Buertai coal mine is more reasonable to take 250 meters,and the width of roadway pillar is designed to be 20 m.
