针对井下充填施工工艺研究的欠缺,对某矿采空区设计了一种泵送胶结矸石充填系统及具体的施工工艺步骤。经现场实践应用,该技术工艺有效降低了工作面的“三量”值,矿压显现缓和,达到了较好的消化矸石与支撑顶板的充填效果。 Aiming at the lack of research on downhole filling construction technology, a pumping cement gangue filling system and specific construction process steps are designed for the gob of a mine. The field practice and application of the technology to effectively reduce the working face of the “three” value, mine pressure appears to ease, to achieve a better digestion gangue and supporting roof filling effect.
