摘要
充填矸石的级配特征对其压缩性能有较大的影响。在济宁3#井井下矸石筛分实验基础上,总结了充填矸石的级配特征,并对其进行了相应的压缩实验,获取了井下原生矸石的压缩性能数据。研究成果为矸石减沉效果评价、级配改良奠定了数据基础。
Gradation Characteristics of filling refuse have a great effect on compression of filling refuse. Based on underground refuse sieving tests of .lining No. 3 shaft, gradation characteristics of filling refuse are summarized and related compression tests are conducted. Compression performance data of primary refuse are obtained. The results lay the foundation for evaluating settlement effect and gradation improvement of refuse.
