制浆系统是整个充填系统的核心。为使超高水材料充填开采技术适应于工业化应用,以陶一矿超高水材料充填开采试验为背景,结合该材料特性.对制浆系统进行了较为深入的研究。确定了制浆系统的形式和生产能力;对半连续制浆系统各组成部分进行了详细设计,并评价了其应用效果。研究表明:超高水材料浆液制备宜选用丰连续制浆系统,该系统运行稳定可靠、制浆能力大、浆液配比准确、操作简便(完全由PLC自动控制),能够满足超高水材料充填开采的制浆要求;该系统占用体积较大,运行环节较多,布置在井下时硐蜜通风备件较差,生产时易产生较大粉尘和噪声,应进行进一步改进;系统更适宜布置在地面上,若布置在井下,应加强硐室的通风管理。
Slurrying system is the core of the whole filling system. In order to let the ultrahigh-water material backfill mining technology adapt to industrialized application, the slurrying system was studied in-depth with the background of the technical test in Tao-one Coalmine. The form of slurrying system and the production capacity were determined. Each part of the semi-continuous slurrying system was designed in detail and its application effect was evaluated. The results show that the semi-continuous slurrying system is the better choice for the preparation of ultrahighwater material grout and the system not only runs stable and reliable and makes accuracy ratio of slurry,but also it is of great slurrying ability and simple operation (all operations are controlled by PLC), satisfying the needs of slurry preparation. However,it has a larger volume and more operation links and underground chambers have poor ventilation. Besides,dust and noise are bigger in the production process. Therefore, further improvement should be done in the future. In general, this system should be placed on the ground, if not, the chamber ventilation management would be strengthened.
