摘要
邢台矿7614充填工作面,充填体支撑采后顶板作用显现,顶板保持了相对完好。在此基础上,对7614充填工作面进行了甩顶网技术试验研究,根据工作面内的顶板完好状态及压力显现情况,预见性的扩大或缩减甩网范围,有效地降低了生产成本,提高了充填工作面生产效率。该技术的试验成功,为今后充填工作面更大范围应用甩顶板金属网工艺提供了可靠的技术依据。
7614 6Bing face in Xingtai Mine, filling the role of body support postharvest roof appeared, the roof remained relatively intact. On this basis, 7614 filling face conducted the top network technology test study, based on the inner face of the roof appeared intact state and the pressure situation, predictability expanded or reduced the scope of rejection network, which effectively reduced production costs and improved filling face productivity. The success of the project provided a reliable technical basis for the future wider application filling face rejection roof metal mesh technology.
