复杂地质工作面注浆加固充填料技术研究

Research on Filling Mining Face Grouting Reinforcement Filling Material Technology under Complicated Geological Conditions

邢台矿现采工作面7623充填工作面地质条件复杂,回采时面临着煤厚异常区、4条中间巷、9条断层,断层落差最大的为9 m,为了保证和提高充填质量,对该工作面运用了注浆加固充填料技术,并对注浆加固效果进行了分析。

Xingtai mine was exploring 7623 fiUing working face, which was under complicated geological conditions. The mine was facing coal thickness abnormal area, four middle roadways and nine faults, among which the largest fall was 9 m. In order to guarantee and enhance filling quality, reinforcement filling material was conducted with grouting technology in this mining face and grouting reinforcement effect was analyzed.
