Research on Safety Improvement of Coal Mining Technology for Fully Mechanized Mining Faces in Large Dip Coal Mines
In order to improve the safety of underground coal mining in a large inclined coal mine,the mining parameters and mining technology were optimized respectively.After on-site use,the improved scheme improved the safety of mining,resulting in an average mining output of 36%per month,an increase of 10.99%in the recovery rate,an increase of 32.8%in the recovery efficiency,an increase of 18 million yuan in the annual output value,and an increase in the economic benefits of the mining area.
