Early-strength mineral seal material.
Background technique
Coal is the main energy in China, however the generation of various disaster accidents is frequently accompanied by during exploitation,
Gas Outburst is most distinct issues, seriously restricts the safe working of coal mine.Hole pumping and mining is the basis of control of coalmine gas
Means, this technology need to be sealed drilling after accomplishing fluently drilling, and the sealing of hole effect of sealing material is particularly important, seriously affects
Gas drainage under suction effect.
The measurement of coal-bed gas pressure at present, extraction borehole direct hole sealing technology have using organic material or inorganic material
It is blocked, including clay manually blocks, mechanic water injection mortar sealing of hole, foaming polymeric materials sealing of hole.Wherein clay method for sealing
Sealed borehole length is shorter, and yellow mud meets water and can soften, and intensity is unable to reach the requirement of sealing of hole；Mechanic water injection mortar sealing of hole cement setting
Speed is compared with slow, volume self-constriction is big, bleed phenomenon is serious, and coal mine environment is complicated, and mining depth is increasingly deepened, cement base sealing of hole
Material can because underground high temperature, high humidity, highly corrosive environment due to cause early strength far from reaching coal seam is anti-reflection to take out with gas
Adopt required requirement.
Chinese patent, CN107118560A disclose " a kind of preparation method of coal mine sealed filling material ", will be organic
Silicone resin is handled with carbon black, carries out ball milling with sodium metasilicate, metakaolin etc., is stirred to obtain high expansion times with auxiliary agent
It counts, the sealing material that setting time is short, and flame retardant property is good, there is good application effect, but early strength is not big enough, 7d is anti-
Compressive Strength reaches 8.4MPa, intensity needed for being unable to satisfy mine seal.Chinese patent, CN107011881A disclose " a kind of
Mining slack coal base hole-sealing grouting material and prepare hole-sealing technology ", by slack coal and Lauxite, ethanedioic acid, silicon powder, hydroxypropyl methyl
The substances such as cellulose, coupling agent, calcium carbonate are mixed, and product setting time is short, at low cost, are improved borehole stability, are mentioned
High resource recovery, the organic matters such as Lauxite have injury to operator's health, and have to environment containing toxic
Evil.
Summary of the invention
Technical problems based on background technology, the invention proposes a kind of early-strength mineral seal material, Ke Yi
Reach higher compression strength in the extremely short time, improve sealing quality, setting time meets pumping requirements, has reached gas
