摘要: 为研究矸石散体在限定空间下经过横向推压之后的固结成型特性,基于充填工作面的充填夯实过程和充填支架捣实机构的工作原理,模拟充填工作面的组成部分,自主研制了一套结构简单操作方便的充填矸石夯实模拟试验台,并应用该模拟试验台研究了推实力和含水量对矸石散体固结成型特性的影响规律。研究结果表明:推实力和含水量对矸石散体的固结成型特性影响呈现正相关,且推实力大于2MPa、含水量为3%时,矸石散体开始表现出明显的固结成型特性。因此,矸石充填夯实模拟试验台的研制及应用,对优化现场矸石充填开采技术提供一定参考意义。

Abstract: Abstract: In order to study the consolidation forming characteristics of the guague bulk after lateral pushing under the limited space, based on the filling and coMPacting process of the filling working surface and the working principle of the filling bracket coMPacting mechanism, the components of the filling working surface are simulated.A set of gangue-filled tamping simulation test bench with simple structure and convenient operation was developed independently. The influence of pushing force and water content on the consolidation forming characteristics of gangue bulk was studied by using the simulation test bench.The results show that the effect of pushing force and water content on the consolidation forming characteristics of gangue bulk is positively correlated. When the pushing force is greater than 2MPa and the water content is 3%, the gangue bulk begins to exhibit obvious consolidation forming characteristics.Therefore, the development and application of the gangue-filled tamping simulation test bench provides a certain reference significance for optimizing the on-site gangue-filled mining technology.
