Influence and Countermeasures of Surrounding Rock Fissure Water on Gas Drainage Effect
Surrounding rock fissure water enters the pumping pipeline through the borehole,which affects the pumping effect.In order to solve this problem,through the analysis of the water inflow and the water outlet point of the surrounding rock fissure water of the floor drainage roadway,the water discharge borehole and the drilling technology are adopted to reduce the water quantity of the borehole,the utility model effectively solves the problem of water accumulation in the pumping pipeline.It improves the effect of pumping,plays a positive role in reaching the standard of the working face,provides more stable gas source for the electric generator,and increases the mine power output to realize economic benefits.
