Description

Additive and new sealing material and the using method of utilizing this additive to prepare for a kind of sealing material
Technical field
The present invention relates to that gain exposed coal coal body is reinforced and gas pressure measurement sealing material additive, be specifically related to additive and new sealing material and the using method of utilizing this additive to prepare for a kind of sealing material.
Background technology
Gas pumping is the fundamental measure of control coal-mine gas disaster accident.In China's coal-mine gas pumping process, the gas pumping amount of most of mines is not up to standard, and its reason key is that mash gas pumping drilling sealing of hole effect can not meet engine request.For this technical barrier, proposed exposed coal coal body and reinforced and gas pressure measurement sealing of hole additive, effectively crack around shutoff boring, improves sealing quality.At present conventional sealing material is as quick setting and high strength swelling property mine sealing material, and its patent No. is 201010172263, and the day for announcing is on September 29th, 2010.Quick setting and high strength swelling property mine sealing material is by 45~50 parts of high-alumina cements, 0.05~0.2 part of citric acid, 10~15 parts, lime, 35~40 parts, gypsum, 0.8~1.2 part of sodium lauryl sulphate is formulated, this material can be under the condition of high water-cement ratio rapid solidification, volumetric expansion in process of setting (maximum degree of free swelling can reach more than 10% in 1 day), but its batching is complicated and be difficult for acquisition, does not have operability.
Summary of the invention
The present invention aims to provide a kind of sealing material additive, is guaranteeing on the basis of sealing quality, sealing of hole effect and a sealing of hole success ratio, solves existing sealing material batching complexity, high in cost of production problem.
Another object of the present invention is to provide new sealing material and the using method of utilizing this additive to prepare.
The technical scheme that the present invention addresses the above problem is as follows:
A sealing material additive, its composition comprises solid accelerating chemicals, rock dust, aluminium powder, described rock dust is inert dust, includes but not limited to limestone powder.Described aluminium powder is to be industrial aluminium powder, and particle diameter is 10~100 μ m.Aluminium powder and now conventional AEA carry out simultaneous test with regard to swelling property and show, not only expansion effect is better but also its cost significantly reduces for aluminium powder.Described solid accelerating chemicals is conventional solid-state accelerating chemicals for existing cement.
In described additive, the weight ratio of solid accelerating chemicals, rock dust, aluminium powder is 50:50:1.25~1.528, and the weight ratio of solid accelerating chemicals, rock dust, aluminium powder is 50:50:1.389 more preferably.
Adopt above-mentioned additive can prepare a kind of new sealing material, its component comprises water, cement, additive, and wherein the weight ratio of cement and water is 0.8~1.5:1, and additive amount is 7%~15% of new sealing material total amount.In addition, be further to improve sealing material performance, additive amount more preferably new sealing material total amount 8%~10%, in described new sealing material, the weight ratio of cement and water can be preferably 1.4:1.Above-mentioned cement is Zones With Common Portland Cement.
The using method of above-mentioned a kind of new sealing material, comprise the following steps: according to material usage, take cement, additive, water, water is joined in anhydrous sealing material and mix even, then immediately sealing material is injected to after fixing on working face and expands, can realize sealing effect.
Adopt this sealing material can also prepare a kind of anhydrous sealing material with additive, the component of this anhydrous sealing material comprises cement, additive, and wherein additive amount is 14%~17% of anhydrous sealing of hole total amount of material.The using method of this anhydrous sealing material, comprise the following steps: according to the weight ratio of anhydrous sealing material: water=1.05~1.55:1, take anhydrous sealing material, water, water is joined in anhydrous sealing material and mix even, then immediately sealing material is injected to after fixing on working face and expand, realize sealing effect.For further improving sealing effect, the weight ratio of above-mentioned anhydrous sealing material and water is 1.45:1 more preferably.
The variation of rock dust amount, the hardness f value after can controlling mixed solution and solidifying.The consumption of accelerating chemicals changes can control the initial set used time that mixture solidifies, reduction of erection time; The variation of aluminium powder amount, can control the cubical expansivity after mixed solution solidifies.
The beneficial effect that the present invention obtains:
This additive adopts solid accelerating chemicals, rock dust, aluminium powder, and self is nontoxic, harmless, pollution-free, uses result to show, this additive improves the intensity of sealing material first with rock dust, and and then improves sealing of hole effect by improving surrounding rock structure.
Additive and using method thereof for sealing material of the present invention, can make sealing material expand rapidly, for mine stone door punching coal coal body, reinforce sealing of hole, coal-mine gas piezometry sealing of hole and wind leaking stoppage etc., effectively fissured zone is become flexible in the extraction of shutoff drilling gas, improved boring stopping property, improved the sealing quality of extraction borehole, and the compactness after effectively increasing sealing material and expanding and the stopping property of boring, improved the coal bed gas extraction boring interior crack of hole wall environment around, significantly improve gas pumping effect, extended the extraction phase of drilling gas.Compare with prior aries such as sand-cement slurry, also shortened the sealing of hole time, reduced staff's labour intensity.
The anhydrous sealing of hole materials'use that sealing material of the present invention makes with additive is convenient, and sealing material is short time of coagulation, and ultimate compression strength is large, can operate and can keep good mobility.
This additive cost is declined to a great extent, and totally has good economic and social benefits, uses its various sealing materials of preparing to have important popularizing application prospect in the coal bed drilling gas pumping sealing of hole of China.
