为了保证采区工作面顶板的稳定性,尤其是抗压强度较低的风氧化带,需要对其进行注浆加固。本文通过对注浆岩层的选择,划定注浆的范围,确定注浆扩散半径、注浆压力、材料配比、注浆量进行注浆的施工,依据注浆的结束标准和质量标准,阐述了地面预注浆加固的注浆工艺。
為瞭保證採區工作麵頂闆的穩定性,尤其是抗壓彊度較低的風氧化帶,需要對其進行註漿加固。本文通過對註漿巖層的選擇,劃定註漿的範圍,確定註漿擴散半徑、註漿壓力、材料配比、註漿量進行註漿的施工,依據註漿的結束標準和質量標準,闡述瞭地麵預註漿加固的註漿工藝。

In order to guarantee the stability of mining coal face roof, especially low compressive strength of the wind oxi-dized zone, need to be grouting reinforcement. In this article, through the selection of grouting strata, delimit the scope of the grouting to determine diffusion radius, grouting pressure, grou-ting materials and grouting and grouting amount, grouting con-struction, according to the standard and quality standard, the end of the grouting ground grouting reinforcement grouting process is expounded.
