技术领域technical field
本发明涉及一种矿用充填密闭材料及制备装置。The invention relates to a mine filling and sealing material and a preparation device.
背景技术Background technique
在煤矿掘进、回采作业时，不可避免地会产生冒落、片帮，形成孔洞。这些孔洞经常造成瓦斯积聚，不仅提高了瓦斯爆炸的危险性，而且在具有自燃倾向的煤层还可造成自燃发火。因此，只有及时填充这些孔洞，才能确保安全生产。我国煤矿通常采用在冒落地点架木垛、填沙浆等方法进行处理，但这些方法费时、费力、施工难度大，且不能保证真正消除事故隐患。另外，采空区不隔离，影响井下通风，国内传统的防爆密闭墙多为砖墙结构，施工用砖块、砂、水泥等进行垒砌粘结，此法劳动量大、效率低，随着煤炭采掘机械化程度的提高，采用传统施工技术难以满足现代化生产要求。因此开发用于煤矿井下的新型充填、密闭材料显得迫在眉睫。During coal mine excavation and mining operations, it is inevitable that caving, slabs, and holes will occur. These holes often cause gas accumulation, which not only increases the risk of gas explosion, but also causes spontaneous combustion in coal seams with spontaneous combustion tendency. Therefore, only by filling these holes in time can safe production be ensured. Coal mines in my country usually use methods such as erecting wooden stacks and filling mortar at the site of the fall, but these methods are time-consuming, laborious, and difficult to construct, and cannot guarantee that the hidden dangers of accidents will be truly eliminated. In addition, the goaf is not isolated, which affects underground ventilation. The traditional domestic explosion-proof airtight walls are mostly brick wall structures, and bricks, sand, cement, etc. are used for construction and bonding. This method is labor-intensive and low-efficiency. With the improvement of coal mining mechanization, it is difficult to meet the requirements of modern production with traditional construction technology. Therefore, it is imminent to develop new filling and sealing materials for underground coal mines.
高分子化学材料进行冒落孔洞充填密闭是国外在七十年代初期发展起来的一项新技术，该技术问世在世界主要产煤国家得到迅速发展。我国在九十年代初期开始研究巷道冒落孔洞化学材料注浆充填密闭技术，并已经取得较好的经济效益和社会效益。但现在用的聚氨酯充填密闭材料存在着价格较高、易燃、反应温度高、反应时产生大量有毒气体的缺点。Filling and sealing caving holes with polymer chemical materials is a new technology developed abroad in the early 1970s. This technology has been developed rapidly in major coal-producing countries in the world. In the early 1990s, our country began to study the sealing technology of chemical material grouting and sealing technology for caves in roadway caving, and has achieved good economic and social benefits. However, the currently used polyurethane filling and sealing materials have the disadvantages of high price, flammability, high reaction temperature, and a large amount of toxic gas generated during the reaction.

本发明的有益效果：本发明采用脂肪醇聚氧乙烯醚、羟乙基甲基纤维素作为表面活性剂能够使得粉煤灰浆液固相颗粒均匀分散，有助于体系稳定。十二烷基硫酸钠和脂肪醇聚氧乙烯醚硫酸钠为主，脂肪醇聚氧乙烯醚、羟乙基甲基纤维素协同作用的有机表面活性剂体系可以提供优越的气泡性能，在搅拌制备过程中可产生充足的气泡。多聚磷酸、羟丙基淀粉醚、可再分散乳胶粉构成的有机胶粘体系能够提供稳定快速的胶粘性能，能够实现渗流分散后在室温条件下20min内快速形成稳定的充填体系。水泥、石膏、熟石灰构成的复合固相体系促进粉煤灰的水化反应，使得固相物质快速固化，特定的玻纤增强材料的物理性能，泡沫抗压性能优异。同时显著降低石膏、水泥、熟石灰等用量，主要使用成本低、质量轻的粉煤灰为主材；经济效益好；同时又保障气泡性能和物理性能。Beneficial effects of the present invention: the present invention uses fatty alcohol polyoxyethylene ether and hydroxyethyl methyl cellulose as surfactants to uniformly disperse the solid-phase particles of the fly ash slurry and contribute to system stability. Sodium lauryl sulfate and fatty alcohol polyoxyethylene ether sodium sulfate are the main ingredients, and the organic surfactant system of fatty alcohol polyoxyethylene ether and hydroxyethyl methylcellulose can provide excellent bubble performance. Sufficient air bubbles can be generated during the process. The organic adhesive system composed of polyphosphoric acid, hydroxypropyl starch ether, and redispersible latex powder can provide stable and fast adhesive performance, and can quickly form a stable filling system within 20 minutes at room temperature after seepage dispersion. The composite solid phase system composed of cement, gypsum, and slaked lime promotes the hydration reaction of fly ash, making the solid phase material solidify quickly, and the specific physical properties of glass fiber reinforced materials, and the foam has excellent compressive resistance. At the same time, the amount of gypsum, cement, slaked lime, etc. is significantly reduced, and fly ash with low cost and light weight is mainly used as the main material; the economic benefit is good; at the same time, the bubble performance and physical performance are guaranteed.
现有技术中因为石膏、水泥、熟石灰用量增大以后发泡效果差或者难以气泡，所以也有粉煤灰用量较大的技术方案；但粉煤灰用量直接导致材料的抗压、粘接性能降低，实践使用中需要配合其他复杂的材料增强措施。而充填密闭材料用量极大，工艺复杂、成本高都影响推广和使用。本发明通过复合气泡和有机粘合系统的建立，成功地解决了现有技术中这一难题。同时材料阻燃性能优良，工艺简单、成本低廉，无机材料为主，无分解、无毒无害，可以大量使用也不会带来安全隐患。且泡沫流体渗透性能好，凝固快速，时间可通过三种胶粘物料用量适当调整。满足煤矿及其他各种矿区充填密闭使用的需求。In the prior art, because the foaming effect is poor or difficult to bubble when the amount of gypsum, cement, and slaked lime is increased, there is also a technical solution for using a large amount of fly ash; however, the amount of fly ash directly leads to a decrease in the compression resistance and bonding performance of the material , in practical use, it needs to cooperate with other complex material enhancement measures. However, the amount of filling and sealing materials is huge, the process is complicated, and the cost is high, which affects the popularization and use. The present invention successfully solves this difficult problem in the prior art through the establishment of composite air bubbles and an organic bonding system. At the same time, the material has excellent flame retardant performance, simple process, low cost, mainly inorganic materials, no decomposition, non-toxic and harmless, and can be used in large quantities without causing safety hazards. Moreover, the foam fluid has good permeability and fast solidification, and the time can be adjusted appropriately through the dosage of three kinds of adhesive materials. It meets the needs of coal mines and other various mining areas for filling and sealing.
