The number three ringed mountain centering on Tangxia town, with east-west length about23 kilometers, and the south-north about16 kilometers; the structure is not very intact, appears a fragmentized ellipse.
Design and actualize of grouting project on fragmentized goaf groundwork
Through this experimentation, it indicates that the sampling bit added pumping hole ADAPTS to drilling in most fragmentized strata.
The combinatorial separation include selective fragmentized separation, primary election and manual election, magnetic separation, difference speed fragmentized separation and auto-transmission line of MSW.
