摘要
通过室内土工试验,研究了煤矸石的矿物成分、颗粒级配、压实特性及抗剪强度与压实度的关系。结果表明,煤矸石的矿物成分与粘土很相似,易压实,将煤矸石回填作为建筑用地在技术上是可行的。
A series of soil experiments on mineral composition, size distribution, mineral composition the relationship of shear strength and compactness of coal waste were carried out. The results shows that mineral composition of waste was nearly same as soil and compressed easily, backfilling waste as ground is feasible. The results of mineral composition the relationship of shear strength and compactness will be references for design and construction of coal waste backfilling.
