Description
技术领域technical field
本发明涉及井下矸石分选充填系统及方法，尤其适用于半煤岩巷道等含矸率较高、且需要煤矿井下工作面采空区的矸石分选回填。The invention relates to an underground gangue sorting and filling system and method, and is especially suitable for gangue sorting and backfilling in semi-coal and rock roadways and the like that have a high gangue content and require goafs in underground working faces of coal mines.
技术背景technical background
矿产资源是人类社会的宝贵财富，是人类社会赖以生存和发展不可缺少的物质基础，但矿产资源的过度开发不可避免地会导致矿山原有的生态环境改变：如植被破坏、废石成山、地下水下降、占用良田、河道改迁、地表塌陷、水质污染、污水排放以及大量尾矿堆放等。而煤炭生产排出的大量矸石堆积成矸石山，占用了大量农田和绿地，形成地表污染。另外，把矸石从井下运到地面以及把充填物从井上运输到井下，需要投入大量的资金。因此，实施井下矸石充填不仅减少井下矸石运输提升量，缓解矿井辅助运输压力，而且能减少地面矸石占地，保护自然环境，社会效益前景良好。Mineral resources are the precious wealth of human society and the indispensable material basis for the survival and development of human society. However, the overexploitation of mineral resources will inevitably lead to changes in the original ecological environment of mines: such as vegetation destruction, waste rocks forming mountains, The decline of groundwater, the occupation of fertile land, the relocation of river courses, surface subsidence, water pollution, sewage discharge, and the accumulation of a large number of tailings, etc. However, a large amount of gangue discharged from coal production has accumulated into gangue hills, occupying a large amount of farmland and green space, forming surface pollution. In addition, transporting gangue from the underground to the surface and transporting the filling from the well to the underground requires a large amount of investment. Therefore, the implementation of underground gangue filling not only reduces the amount of underground gangue transportation and eases the pressure of mine auxiliary transportation, but also reduces the land occupation of ground gangue, protects the natural environment, and has a good prospect for social benefits.
井下矸石分离充填技术是在井下对采下的煤矸混合料进行选择性破碎，利用煤矸的硬度差异，相同的冲击力使硬度较低的大块煤碎成小块，而大块矸石基本保持原来的块度，然后通过筛子把破碎的煤和未破碎的矸石分开，被通过运输系统提升上井，而矸石在井下按一定级配破碎为粗细不等的颗粒和微粉，并充分混合，构成一种可泵塑性流动稠料，经管道被泵入采空区进行充填。如果在破碎矸石冲参入一定比例水泥或粉煤灰可增加充填物凝固后的强度，可用于充填采矿法，进行三下采煤，提高煤炭回收率。The underground gangue separation and filling technology is to selectively crush the mined coal gangue mixture underground. Using the hardness difference of coal gangue, the same impact force breaks the large coal with low hardness into small pieces, while the large gangue is basically Keep the original lumpiness, then separate the broken coal and unbroken gangue through a sieve, and then lift it up the well through the transportation system, while the gangue is broken into particles and fine powders of different sizes in the underground according to a certain gradation, and fully mixed to form a coal mine. A kind of pumpable plastic flow thick material, which is pumped into the goaf through the pipeline for filling. If a certain proportion of cement or fly ash is added to the crushed gangue, the strength of the filling after solidification can be increased, and it can be used in the filling mining method to perform three-down coal mining and improve the recovery rate of coal.
