综采面放顶煤液压支架选型与参数确定研究

Research on Selection and Parameter Determination of Hydraulic Supports for Top Coal Caving in Fully Mechanized Mining Face

为确定麻地沟煤业13204工作面放顶煤液压支架的最佳搭配,确定支架选型与参数,结合工作面基本情况与顶板窥视结果的相关资料,先确定液压支架选型,然后采用估算法分别确定各项参数。实践证明,所选定的液压支架为麻地沟煤业13204工作面创造了必要的安全回采空间,支护效果良好,产生了良好的经济效益。

In order to determine the best matching of hydraulic support for top coal caving in 13204 working face of Madigou Coal Industry,determine the support selection and parameters,combining with the basic situation of working face and the relevant data of roof peep results,the hydraulic support selection is determined first,and then the parameters are determined separately by the estimation method.Practice has proved that the selected hydraulic support has created the necessary safe mining space for the 13204 working face of Madigou Coal Industry,the supporting effect is good,and good economic benefits have been produced.
