摘要
通过对水在采空区遗煤氧化及自燃的作用机理两重性的分析以及实验室试验与现场应用实际效果研究 ,证实了笔者提出的清水灌注措施是一种新的、经济有效的、操作简便的防治采空区遗煤自燃的技术措施。同时 ,对传统的黄泥灌浆技术措施中的泥浆浓度要求提出了新的看法。此外 。
By analyzing the double meaning of the effect mechanism of water on the oxidation and spontaneous combustion of residual coal in goaf, and through investigation of the results both in laboratory and field practice, it is confirmed that water pouring, which is suggested by authors, is a new, economic, efficient and easy to operate measure for controlling the spontaneous combustion of the residual coal in goaf. At the same time, a new concept concerning the slurry concentration in the traditional slurry grouting technique is put forward. Furthermore, the cycle of water pouring into the goaf is especially investigated.
