Coal seam grouting material and application method thereof
The invention relates to the technical field of green coal mining, and particularly discloses a coal seam grouting material and an application method thereof. The coal seam grouting material comprises the following components in parts by weight: 100-120 parts of coal solid waste raw powder, 40-50 parts of a solid waste-based cementing material and 165-185 parts of water, the coal solid waste raw powder comprises coal gangue powder, the solid waste-based cementing material is formed by grinding a mixture and calcining the ground mixture at 900-1000 DEG C, and the mixture comprises coal gangue and carbide slag. The solid waste-based cementing material is used for replacing a part of coal solid waste raw powder, the possibility of segregation of the coal seam grouting material in the pumping process is reduced through the cohesiveness of a gel product, the pipe blocking phenomenon of the grouting material is reduced, the pumpability of the grouting material is improved, and the difficulty of grouting operation is reduced.
本申请涉及煤炭绿色开采技术领域，具体公开了一种煤层注浆材料及其应用方法。所述煤层注浆材料包括如下重量份的组分：煤炭固废原粉100‑120份，固废基胶凝材料40‑50份，水165‑185份，所述煤炭固废原粉的组分包括煤矸石粉，所述固废基胶凝材料由混合料经过粉磨后在900‑1000℃煅烧而成，所述混合料的组分包括煤矸石和电石渣。本申请使用固废基胶凝材料替代了一部分煤炭固废原粉，利用凝胶产物的粘聚性减少了煤层注浆材料在泵送过程中发生离析的可能，有助于减少注浆材料的堵管现象，改善了注浆材料的可泵性，有助于降低注浆作业的难度。
