【摘要】 依据椭球体放煤理论,研究了煤层地质赋存条件与放煤参数之间的关系,分析总结了放煤步距、采放比、放煤间距各参数对放出体的影响,从而能够比较合理地确定放煤工艺参数及选用设备;对常用的放煤方式提出了一些有意义的见解,有针对性地为解决实际问题提供理论依据.更多还原

【Abstract】 Based on ellipsoid theory,the relationship between the geological conditions and coal caving parameters was studied.The effects of drawing interval,mining ratio and caving spacing were analyzed and summarized.The reasonable selection of process parameters was carried out.Meaningful insights were made about some common ways of coal drawing methods,provideing a theoretical basis for solving practical problems.更多还原
