要保证采区顶板风氧化带的稳定性,就需要对其岩体进行注浆加固。本文通过了解注浆区域顶板风氧化带的岩体结构分布,分析岩体可注性的影响因素和裂隙岩体渗透的几何参数,利用现场压水试验,统计注浆段地层的单位吸水率,得到吕荣值,判断岩体的可注性。
要保證採區頂闆風氧化帶的穩定性,就需要對其巖體進行註漿加固。本文通過瞭解註漿區域頂闆風氧化帶的巖體結構分佈,分析巖體可註性的影響因素和裂隙巖體滲透的幾何參數,利用現場壓水試驗,統計註漿段地層的單位吸水率,得到呂榮值,判斷巖體的可註性。

To ensure the stability of mining roof wind oxi-dized zone, it is necessary to carry out grouting in rock mass. In this paper, through the understanding of rock mass structure of regional distribution of grouting roof wind oxidized zone, anal-ysis of rock mass permeability factor and geometric parameters of fractured rock mass effect of injection, the use of field water pressure test, the unit absorption rate of statistical grouting stra-tum, get LV capacitance value, judging the groutability of rock mass.
