在分析综放工作面顶煤运移影响因素的基础上,建立了顶煤运移规律数学模型,并通过对开滦集团部分煤矿综放工作面的实际参数计算,验证了数学模型的有效性,为今后的放顶煤工艺提供了数据依据。
Based on the analysis of the influencing factors of top coal movement in fully mechanized top coal caving face, a mathematic model of top coal movement was established and the validity of the mathematical model was verified by calculating the actual parameters of fully mechanized coal caving face in some coal mines of Kailuan Group , Provided the data basis for the caving coal technology in the future.
