摘要
为了提高采空区的充填效率,需要对影响充填装置充填效率的各种因素进行分析研究。在干式充填气力输送实验中,通过改变影响节流孔板特性的结构参数,包括开孔形式和开孔面积,研究其对采空区充填效率的影响。研究结果为工程的实际应用提拱依据。
In order to improve the efficiency of goaf filling,the various factors that influence packing efficiency of filling device should be studied. In dry filling of pneumatic conveying experiments,through changing the structural parameters of the throttling orifice characteristic,including the opening form and opening area,the influence on the efficiency of goaf filling is studied. The research results provide the basis for the practical application of engineering.
