摘要:

根据平朔井工三矿39107综放工作面赋存条件以及风氧化带颗粒组成分析,确定采用马丽散对风氧化带注浆加固;根据传统注浆工艺与间歇式注浆对比实验结果可知,间歇式注浆工艺可人为控制注浆渗流半径、更易形成网络骨架;对井工三矿风氧化带进行超前注浆加固,通过钻孔窥视法检测可知间歇式工艺注浆加固与渗透效果较好,可节约注浆材料费约56%。因此间歇式注浆工艺具有较好的应用前景。

Abstract:

The article is based on the technical conditions of 39107 caving face and particle composition analysis result in Pingshuo Coal Industry Company No.3 Coal Mine, determine the use of Malisan grouting reinforcement to wind oxidation zone; through comparative experimental results both traditional grouting technology and intermittent grouting technology, intermittent grouting technology may artificially control grouting seepage radius and apt to form network skeleton; and carry on advance pregrouting reinforcement to wind oxidation zone, by drilling peep france detecting and showing that reinforcement effect and penetration effect of intermittent grouting technology is better, saving grouting materials cost is 56%. So Intermittent Grouting has extensive Application prospects.
