摘要
在分析和研究放煤口位置对放煤参数及放煤量影响的基础上 ,应用松散介质放出椭球体理论 ,建立了确定合理放煤口位置的数学模型 ,研究结果与生产中的实际情况十分吻合 ,说明该理论的正确性 。
On the basis of an analysis of the effects of drawing opening position on the parameters and output for coal drawing, a model of optimal drawing opening position was established based on the theory of drawing ellipsoid in loose medium.The conclusions of this study conform to the actual situation in production.It shows that theory itself is correct.The optimal support can be induced depending upon the varying conditions.
