By using subarea - subsection mining method , multi - channel layout program , heidaigou open - pit coal mine has overcomed the technological continuity problems appearing in bench combination and has fully improved the capacity of existing equipments , so that the transportation distance has been reduced and enormous economic benefits have been gained 在此过程中，黑岱沟露天煤矿通过分区分段开采、多通道布置等方案，克服了并段台阶工艺接续过程中出现的问题，最大限度的增加现有设备生产能力，减少运距，创造了巨大的经济效益。
The theory of landscape ecology about drastic disturbance of landforms has been richened . a practical way could be found to identify the final direction of artificial ecosystem succession . moreover , the results can be applied into study the land reclamation and ecological rehabilitation of the developed opencast mines and developing ones in loess plateau 本研究结果的学科价值:丰富了极端生境下剧烈扰动地貌的景观生态学理论，为确定人工正确诱导下的矿区生态演替方向提供了可借鉴的方法和途径;应用价值主要体现:研究结果适宜于我国黄土高原正在开采和将要开采的大型露天煤矿的土地复垦与生态重建。
