在具有含水裂隙岩层的复杂矿山地质条件下建设井筒时,普遍采用岩石注浆法。该方法能够建立保护性的防渗帷幕、减少岩石的透水性及将井筒涌水量降至规定标准,从而降低工程造价及提高井筒建设速度。在岩石注浆工程中检测岩石状态及注浆帷幕形成
Rockbolt grouting is commonly used when building wellbores under complex mine geological conditions with water-bearing fractured rock layers. The method is capable of establishing a protective impermeable curtain, reducing the water permeability of the rock and reducing the well water inflow to a specified standard, thereby reducing the construction cost and increasing the speed of wellbore construction. In the rock grouting test rock status and grouting curtain formation
