神府─东胜煤田开发对乌兰木伦河河道淤积与输沙的影响

神府─东胜煤田自1987-1993年开发以来，河道露天采煤、矿区建设排弃的大量土石碴堆积于河道或岸坡，导致河床淤积严重，输沙量骤增.乌兰木伦河下游50km净淤积1310.5×10⁴m³，平均年增加187.2×10⁴m³，输沙量比采矿前增加70%，平均年增加735×10⁴t.文中对河道淤积的泥沙来源和采矿排弃物流失量进行了深入分析，并提出该流域治理的建议与对策.

The influence of Shenfu-Dongsheng coal mining on river bed siltation and sediment load of Wulanmulun river Wulanmulun river

A great quantity of abandoned earths, stones and dregs from open mining coal in the river and construction of coal field are piled up in the bed of Wulanmulun river, as a result deposition of river-bed and sedinment load are both remarkably rised since Shenfu-Dongsheng coal field mining in 1987. About 1310.5 ×10⁴m³ net sediments silted and 361.5 ×10⁴m³ mixtures of sand and stone piled in the river bed of 50 km in lower reaches after coal mining, comparing with before mining average annual sediments increases by 187.2 ×10⁴m³ and the sediment load of the river increases by 70 percent and average anmual sediment load increases.The sediment resource of river siltation and increasing of soil loss are analysed, and some suggestion and countermeasure on reclamation planning of the river basin are also presented in the paper.
