Preparation and adding method and preparation equipment of roof-contact agent for filling coal mine cemented gangue
The invention discloses a composite roof-contacted agent with expansion and flow promotion functions for filling coal mine cemented gangue and an adding method. According to the top-contacting agent, the problem of poor top-contacting of various filling bodies caused by poor slurry fluidity, high bleeding and large shrinkage in a coal mine filling project is comprehensively solved through the expanding agent, the expanding agent coating agent, the flow promoting agent and the flow promoting agent slow-release agent. Moreover, after being coated, the expanding agent can delay the time of expansion and prevent the problems of pipe blockage and invalid expansion caused by expansion in a pipeline, and the flow promoting agent slow-release agent can continuously release the flow promoting effect and improve the flowability, so that various roof contact problems of coal mine cemented gangue filling projects are comprehensively solved, the mixing amount is low, the use is convenient, and the application prospect is wide. The invention further discloses an adding device of the composite roof-contacted agent with the expansion and flow promotion functions for a cemented gangue filling material preparation system.
本发明公开了一种兼具膨胀与促流功能的煤矿胶结矸石充填用的复合型接顶剂以及添加方法，该接顶剂通过膨胀剂、膨胀剂包覆剂、促流剂以及促流剂缓释剂来综合解决煤矿充填工程中因浆体流动度差、泌水高、收缩大导致的各种充填体接顶差的问题。而且，膨胀剂经包覆后可以延缓膨胀发生的时间，防止膨胀在管道中发生导致堵管和无效膨胀问题，促流剂缓释剂可以使促流作用持续释放，提高流动性，从而综合性解决煤矿胶结矸石充填工程各类接顶问题，且掺量低、使用方便，本发明还公开了一种兼具膨胀与促流功能的复合型接顶剂用于胶结矸石充填材料配制系统的添加装置。
