Based On The The Gangue Paste-like Cement Filling Method Under The Control Of Strata Movement

The disquisition of the filling like-plaster of the coal detritus in bothcontrolling cover rock and the earth's surface remotiong disciplinarian is a taskof great significance and research value. This thesis aim at accumulating a greatdeal detritus in ming and overstocking a great deal high grade coalcolumniation in growing ensure public security jamb in sun cun coal mine ofxin wen group, and it mainly involves the following aspects:1. After referring to a large amount of literature materials, it summarizesthe present state and the means of the research on controlling cover rock andthe earth's surface remotiong disciplinarian and controlling technic, It gives adetail introduction about filling controlling technic, which can eliminate thesocial effects of pollution of coal detritus and become the depose to treasure.2. A brief summary of the basic rules causing the sinking, which includesan introduction of the district, the form of motion and the process of thedamage of superimposed rock, and an introduction of the range of surfacesinking, the forms of surface moving damage and the basic surface distortionparameters.3. The filling body mainly make up of coal detritus, after roomexperiment, determing physics and mechanics parameter, confirming the bestinverse proportion of the filling body; It gives a detail disquisition about thecharacters of the filling body, the mechanics mechanism of the filling body insupporting wallrock and controing underground press active, glue-coagulatemechanism of powder coal and like-plaster cementation filling mechanism bothglue-coagulate and coal detritus.4. The thesis also sums up the constitutive relationship of the elasticity andplasticity of the soil and briefly accounts for the Drucker-Prager Model and thechoice of the model parameters. It particularly introduces that how to realizethe numerical analysis of the soil non-linear mechanics by ANSYS. Through aconcrete project it explains how to use the ANSYS to have the numericalanalysis on the filling like-plaster of the coal detritus in both controlling coverrock and the earth's surface remotiong disciplinarian of the mining subsidence,and the calculating result is applied to the project.5. The conclusion after having the numerical analysis of the disciplinarian the filling like-plaster of the coal detritus in both controlling cover rock and theearth's surface remotiong:(1)Betimes filling mining subsidence after mining coal bed, the effect ofminishing both surface sinking and level distortion is makkedness.(2)After filling mining subsidence, the range of the sinking basin doesn'thave an obvious change and the sinking difference on the verge of the basinbecome more small and the figure of the sinking become more gent.(3)After comparing and analysing the seven different blue print, ensurefurthest step.6. On the basis of the above research, It gives a detail introduction aboutthe filling economy like-plaster of the coal detritus of blue print designing andconduit feeding accounting, and radically settle the issue of accumulating agreat deal detritus in ming and overstocking a great deal high grade coalcolumniation in growing ensure public security jamb.
