黑岱沟露天煤矿土地复垦中的几个关键问题

根据黑岱沟露天煤矿工艺特点和矿山具体条件,对黑岱沟露天煤矿的土地复垦规划进行了研究.认为土地复垦,尤其是其中的工程复垦应和采矿生产工艺及排土工艺紧密结合起来,纳入采矿生产计划之中,提出了外排土场覆土工艺方式和场地整治工程的具体要求.根据覆土的理化性质和矿区实际情况,提出了复垦土地的土壤改良方法.经种植实验研究选择出适宜于矿区条件的先锋植物和适宜树种,建立了不同立地条件下的植被配置模式.然后,就复垦土地的再利用方式作出了总体规划,并进行了灌溉系统的方案设计和土地复垦的经济评价.

Several key questions of reclamation in open pit coal mine of Heidaigou

According to the technological characteristics and the real conditions of Open Pit Coal Mine of Heidaigou, planning of the reclamation of Open Pit Coal Mine of Heidaigou was researched. It was considered that the reclamation, in especial degraded engineering, ought to be combined closely with the process of production and of discharge; and is one of the parts of mining planning. The method of discharging of waste soil and rock and of the soil improvement of the reclamation land at discharged area out of the open pit were put forward. As a result of the planting experiments, the pioneer plants and the seeds of trees suitable for the nature conditions of the mine area were selected. The models of vegetation disposition in the different soil and topographic conditions were set up. Then, the reusing modes of reclamation land were planned generally, and the scheme planning of the irrigation system and the economical evaluation of the reclamation were made.
