Study on the fully mechanized face with large mining height passing through geological structures
In response to the difficult cutting of coal shearer and abnormal mine pressure during fully mechanized mining face with large mining height passing through the intrusive large cross-section erosion zone,taking a fully mechanized mining face with large mining height in Bulianta Coal Mine as an example,the detection method for the erosion zone in the fully mechanized mining face with large mining height by directional drilling technology was summarized.Based on the results of directional drilling,the method of passing through the erosion zone in the mining face was determined,and the key technologies and the law of mine pressure behaviors were summarized and analyzed,which provided some reference for fully mechanized mining face with similar geological conditions passing through erosion zones.
