Superfine, micro-expansive and high-strength grouting material for deep well mine
The invention discloses a superfine, micro-expansive and high-strength grouting material for a deep well mine. The grouting material is prepared by mixing the following raw materials in parts by weight: 25-32 parts of cement, 3-5 parts of lime, 5-8 parts of gypsum, 8-12 parts of blast furnace slag and 15-22 parts of dolomite powder. The grouting material prepared by the invention has the characteristics of being superfine, micro-expansive and high in strength, and multiple experiments show that the grouting material is short in coagulation time period, the slurry loss in the stratum can be reduced, the stone body has certain micro-expansibility, the stone body is high in strength, cracks can be more fully plugged and filled, and ideal water plugging, reinforcing and seepage-proofing effects are achieved.
一种用于深井矿山的超细、微膨胀、高强注浆材料，按以下原料重量份配比混合而成：水泥25～32份、石灰3～5份、石膏5～8份、高炉矿渣8～12份、白云石粉15～22份；本发明配制的注浆材料具有超细、微膨胀、高强度的特点，经多次实验表明，该注浆材料凝结时间段、可减少在地层中的浆液损耗，结石体具有一定的微膨胀性，结石体强度高，可更充分地封堵和充填裂隙，达到理想的堵水加固和防渗效果。
