Embodiment
Certain ore deposit adopts full tailings-Water Quenching Slag to carry out paste body filling.The fineness of full tailings is thinner, and-20um content is between (76%～83%).From the last mortar in dressing-works, it is concentrated to flocculate in thickener, mixes back preparation lotion again with cement, Water Quenching Slag, and gravity flow is transported to the down-hole stope then.In production phase in the early stage, not solidification phenomenon of stope filling repeatedly occurs, stope normally carries out back production near having influence on.For this reason, carried out multiple Study on Measures, comprised and add lime white, high efficiency water reducing agent, various hardening accelerator, but can not thoroughly solve the problem of full tailings slow setting.Fully analyzing on the basis of full tailings slow setting reason, think that the major cause of slow setting is that full tailings fineness is meticulous, thereby have influence on the normal hydration reaction of cement.Therefore must add setting accelerator from the jointing compound prescription, could shorten the time of coagulation of full tail lotion, improve the performance of condensing of full tail lotion.
Present method is that carry out on the basis with the ordinary Portland cement, although the condensation effect of other special cement also can satisfy processing requirement, and the restriction of being originated, and cost is higher.Setting accelerator 4 carries out proportioning with jelling agent 1, filling aggregate 2, water 3, and tests the setting time of the lotion of its composition, as shown in Figure 2.Setting accelerator 4 is a fluent meterial, and modulus is 2.6～2.8.With the increase of setting accelerator 4 additions, lotion sharply shortens time of coagulation.When addition surpass jelling agent weight 30% the time, be about 1h time of coagulation, rate of set is too fast.For this reason, the recommendation interpolation scope of the setting accelerator 4 in this ore deposit is 10%～30% of a jelling agent weight.
The interpolation of setting accelerator 4 is carried out on the underground filling main pipe, after using maturation, will move on to face of land Filling Station, directly joins in the stirrer.Measuring apparatus 5 is key equipments of realizing that setting accelerator quantitatively adds, can change the consumption of setting accelerator 4 at any time according to the consumption of preparation station, face of land jelling agent, enables to guarantee in the interpolation scope of design.One end of measuring apparatus 5 and setting accelerator container are connected with water tank (cleaning measuring apparatus 5), and the other end links to each other with one section small diameter pipeline 6 on the filling main pipe.The radius of small diameter pipeline is 75mm, and length is 10m.After measuring apparatus 5, install a unidirectional reverse checkvalve 7 additional, prevent that jelling agent from flowing backwards, and stops up measuring apparatus 5.
Commerical test is filling lotion 305m altogether
3Actual proportioning is a cement: Water Quenching Slag: full tailings is 1: 1.36: 10.58, and lotion concentration is 76%, and setting accelerator 4 additions are 10.8% of cement weight.From the presetting period of the lotion sample of stope collection be 450min, its 7 days, 14 days and 28 days intensity are respectively 0.642MPa, 0.794MPa and 0.870MPa.The filling stope reached the condition of removing barricade after three days, its early strength is greatly enhanced, and has eliminated because of filling slurry long influence to production schedule time of coagulation.
