Abstract
The invention relates to a cementing material used in mines. It contains smelting waste slag and lime in the weight ratio of 1 to 0.1-0.5. The smelting waste slag can be iron-making slag, copper-smelting slag, lead-smelting zinc slag and the like. The manufacturing method is extremely simple. The construction by using the cementing agent has simple process and low energy consumption, so the filling cost is low. But the cementing agent has good cementing property, strong binding force with river sand, tailing, rock block, broken stone and the like, high strength of a filling body, and more remarkable effect especially for a mine with high sulfur content.
Description
The present invention relates to the employed gelling material in mine.
At present, the employed gelling material overwhelming majority in the mine of domestic employing cemented filling method is a silicate cement.The cement price height, the cement consumption is generally 100-300kg/m
2, it is about 60% that the gelling material cost accounts for filling cost, account for the about 20-30% of mining cost, and formed strength of filling mass is not high, particularly makes filling aggregate with tailings, and the gelling material consumption is bigger, and shared cost proportion is also big.In addition, for the higher mine of sulfur-bearing, because the oxidation of sulfide, it is acid that pit water is, and tailings also sulfur-bearing is higher, and is bigger to the strength of filling mass influence.Domesticly begin to develop the gelling material of substituted for silicon acid salt cement from the end of the eighties, as high-water material, full water material and red mud consolidating material etc.High-water material and full water material belong to sulplo-aluminate or aluminate serial gelling material, and maximum characteristics are that combined water is big, and the presetting period is short.But material price is than the silicate cement height, the ratio requirement strictness.Red mud jointing compound main raw material is a red mud, and the red mud jointing compound has cheap, and strength development is very fast, and characteristics such as stable long-term strength growth, still, red mud is the industrial waste of alumina producer, therefore this jointing compound is subjected to the restriction of region, can only use in the mine near alumina producer.
The existing approach of melting waste slag that utilizes mainly contains two kinds, and the one, as wherein a kind of raw material of making cement; The 2nd, as wherein a kind of raw material of brickmaking.These two kinds of waste residues that method is utilized all need could be utilized at last through after certain art breading, for example, during brickmaking, need earlier raw material to be mixed, and are pressed into adobe by brick press then, after sintering just can obtain the available product.
It is cheap to the purpose of this invention is to provide a kind of raw materials cost, makes very easy cementing agent for filling in mine.
Cementing agent for filling in mine provided by the invention contains melting waste slag and lime, and its weight ratio is 1: 0.1-0.50.
On the basis of above-mentioned essentially consist, can add flyash or (with) gypsum; Also can be used with cement.Its weight proportion scheme is as follows:
(1) melting waste slag: lime: flyash=1: (0.1-0.6): (0.0.8);
(2) melting waste slag: lime: gypsum=1: (0.1-0.6): (0.1-0.25);
(3) melting waste slag: lime: flyash: gypsum=1: (0.05-0.5): (0.3-0.8): (0.1-0.6).
(4) melting waste slag: lime: cement=1: (0.05-0.5): (0.4-0.8).
In melting waste slag, as the ironmaking slag, copper slag refines plumbous cadmia, and antimony regulus slag etc. contain available composition, SiO
215-50%, CaO 10-40%, Al
2O
33-25%, these compositions are available.The present invention adopts the lime be easy to get for the main raw material that adds, and as stimulator, makes cementing agent for filling in mine provided by the invention, can equally with Portland cement directly fill glued.
The preparation process of jointing compound provided by the invention is very simple, only needs melting waste slag is milled to below 200 orders, and the metering mixing of pressing each component gets final product.In when construction, add the filling of can going into the well of an amount of water according to circumstances, identical with general cemented-method.
Provided by the invention is the cementing agent for filling in mine of main raw material with the melting waste slag, and its raw materials for production delime, gypsum all are outward waste materials.Its manufacture method is very simple.Utilize this jointing compound to construct, technology is simple, and energy consumption is low, and filling cost is low.But the glued characteristic of this jointing compound is good, and with river sand, tailings, piece stone, the bonding force of rubble etc. is strong, the strength of filling mass height, and particularly for the high mine of sulfur-bearing, effect is more remarkable.
