Analysis of floor grouting control effect in working face mining under pressure based on comprehensive geophysical exploration
In order to verify the effect of floor grouting control in working face mining under pressure,this paper took the floor grouting project of No.5-104 Face in Fenyuan Coal Industry of Huozhou Coal and Electricity as an example.Before grouting,a variety of(multiple)geophysical exploration techniques were used to comprehensively explore the internal and floor structure occurrence and aquifer water abundance of working face mining under pressure.The working face needed to carry out multiple grouting.After each grouting,geophysical exploration methods were used to verify and guide the next grouting,so as to provide'target area'for grouting control.The comprehensive geophysical data before and after grouting were compared and analyzed to test the effect of grouting control and ensure the safe mining of working face.
