【摘要】：富水軟巖井筒掘進(jìn)過程中,弱膠結(jié)軟巖遇水泥化將形成具有流動特性的泥漿,導(dǎo)致工作面掘進(jìn)和排矸困難,惡化工作面環(huán)境,增加工人勞動強(qiáng)度,嚴(yán)重影響施工速度。為有效解決此問題,提出在工作面泥漿中參入適量的高分子吸水性樹脂、纖維素和多種礦物質(zhì)原料以增強(qiáng)泥漿的稠度,便于排矸。首先通過吸水率試驗(yàn),研究高分子吸水性樹脂、纖維素和多種礦物質(zhì)原料等材料與水有關(guān)的性質(zhì);其次利用水泥跳桌流動度儀對摻入上述材料的流砂泥漿的稠度進(jìn)行檢測,研究高分子吸水性樹脂、纖維素和多種礦物質(zhì)原料對流砂泥漿稠度的影響規(guī)律,確定合適的吸水增稠材料以及配比。研究結(jié)果表明摻入高分子吸水樹脂對增加流砂泥漿的稠度效果最好,纖維素次之,礦物質(zhì)材料對流砂稠度的影響,遠(yuǎn)不如高分子吸水樹脂和纖維素。
[Abstract]:In the driving process of water-rich soft rock wellbore, the weak cemented soft rock will form mud with flowing characteristics, which will lead to the difficulty of driving and discharging gangue in working face, worsen the working face environment, increase the labor intensity of workers, and seriously affect the construction speed. In order to solve this problem effectively, it is put forward that appropriate amount of macromolecular absorbent resin, cellulose and various mineral materials are added to the mud to enhance the consistency of the mud and facilitate the discharge of gangue. Firstly, the water-related properties of polymer absorbent resin, cellulose and various mineral raw materials were studied by water absorption test, and the consistency of quicksand slurry mixed with the above materials was measured by using the cement table fluidity meter. The effects of polymer absorbent resin, cellulose and various mineral materials on the consistency of quicksand slurry were studied. The results show that the effect of polymer absorbent resin on increasing the consistency of quicksand slurry is the best, followed by cellulose, and the effect of mineral material on the consistency of quicksand is far less than that of polymer absorbent resin and cellulose.
