Analysis of Coal Seam Working Face Characteristics and Sur-rounding Rock Control Methods
As an important energy resource,efficient mining and utilization of coal are necessary.However,coal seam working faces operate in complex and ever-changing geological environments underground,and their safety and stability issues are be-coming increasingly prominent.Therefore,this study analyzes the characteristics of coal seam working faces and combines dif-ferent surrounding rock control methods to explore how to effectively respond to changes in geological conditions of working fac-es,in order to improve the safety and efficiency of coal mine production.The monitoring results show that in the fourth week af-ter excavation,the cumulative displacement and subsidence of the top plate of section 1 are about 10 mm,and the cumulative displacement and subsidence of the top plate of section 2 are about 12 mm.This indicates that the timely adoption of surround-ing rock control measures has successfully stabilized the deformation of the roadway,ensuring a good effect of surrounding rock control.Therefore,in-depth research on the characteristics of coal seam working faces and effective application of sur-rounding rock control methods can promote the rational exploitation of coal resources and the sustainable development of min-ing production.
