摘要
掌握膏体充填料浆在采空区中的流动堆积特性,在实践过程中可以为控制充填质量和钻探成本提供依据。以此为出发点,首先引入了膏体充填料浆的堆积形态的描述方法,在此基础之上根据煤矿采空区的特性建立了关于空洞型采空区的充填计算方法,最后结合实例验证了该理论计算方法的可靠性。
Master the properties of flowing and accumulating about paste filling slurry in goaf, can provide a reference for control the quality of filling and the cost of drilling in the process of practice. As a starting point,the paper firstly introduced the description method of the shape of accumulation about paste filling slurry. On this basis,the calculation method of filling and accumulating about hollow goal was set up according to the characteristics of coal mine goal;finally,the practice shows that the model is reliable.
