本文针对我国山西、内蒙、陕西一带近水平煤田的特点,探讨了适宜的露天开采工艺、开采程序、开拓运输系统等主要技术问题和提高近期经济效益的措施。剥岩采用单斗挖掘机一汽车运输开采工艺条件下,划分条区开采,双翼内排;采煤采用露天滚筒式采煤机进行煤矸选采;以及运煤采用汽车—溜井—巷道胶带输送机系统等等。对上述近水平煤田的合理开发有实际意义。
In this paper, according to the characteristics of nearly horizontal coalfields in Shanxi, Inner Mongolia and Shaanxi Provinces in our country, the suitable technical measures of open-pit mining process, mining procedure, developing transportation system and other measures to improve the economic benefits in the near future are discussed. Peeling excavation by a single bucket excavator a car transport mining process conditions, the division of strip mining, wing row; coal mining using open-air roller coal gangue mining; Machine system and so on. This is of practical significance to the rational development of the above-mentioned near coal fields.
