摘　　要：以石槽村煤泥为主要原料进行冷压成型制备型煤,采用单因素实验和正交实验等方法,重点研究黏结剂掺比和配煤比对型煤质量的影响.结果表明,添加少量的A或D黏结剂即可使型煤具有良好的冷压强度.配煤比和D黏结剂掺比是型煤质量指标的主要影响因素,D可与煤粒固化形成高强度的型煤"骨架",但会增加型煤灰分,降低其发热量;配入原煤可提高煤泥型煤发热量,降低灰分,但会降低型煤强度.煤泥单独进行成型时,较优的黏结剂配方为:A掺比5%或D掺比4%;配煤成型时,以配煤比为8(煤泥)∶2(原煤)、D掺比7%为宜.A briquette was prepared with Shicaocun coal slime by cold-pressed process, single factor and orthogonal experiments were adopted to study the effect of the ratio of binder and coal blending on the briquette quality. The results show that adding a small amount of binder A or D could make the briquette having good cold strength. The ratio of coal blending and binder D were the main factors of briquette quality, high strength briquette ＂skeleton＂ could be cured with binder D and coal particles, but the briquette ash content increased and the calorific value reduced. Blended with raw coal would increase the coal slime briquette calorific value and reduce its ash content, but it also will reduce the briquette strength. Forming with coal slime, the optimum formulation was 5% binder A or 4% binder D. Forming with slime and raw coal, the appropriate ratio of coal blending was 8（slime）： 2（coal） and 7% binder D.
