Study of technique simulating test on fully mechanized top-coal caving workface in greater inclined and thick coal seams

This paper carries out an overall similar materials simulation test within a laboratory, contrast to actual measured study of workface with technique parameters selection on fully mechanized top-coal caving in workface 3237 of Zhaogezhuang coal mine in Kailuan with greater inclined and deep mining situation. We have obtained a large number of data and achievements through several methods of testing and observation, to provide reliable references to technique parameters selection on fully mechanized top-coal caving in workface 3237 of Zhaogezhuang coal mine. This technique studies have indicated that it is reliable to prove through practicing in mining of workface and similar materials simulation in laboratory. This method can be used as an important measure of technique parameters selection on fully mechanized top-coal caving.
