为满足设计人员对综采设备选型的需要,情报协作组在1978年组织10个单位进行了现场调查,之后,我们又学习和分析了国内外的一些资料.本文重点介绍采煤机、自移支架和刮板运输机的选型.一、采煤机:综采工作面的采煤机械主要是滚筒机组和刨煤机.1.滚筒机组:其作用是破煤和装煤.固定式滚筒采煤机结构简单,维护方便,无摇臂,机道宽度小.摇臂式滚筒采煤机可调整采高,适应性强,目前使用较多.选择采煤机组主要考虑以下几个方面:(1)具有足够强大的功率,能在各种硬度和有夹石的煤层中使用;在局部地质构造变化地带能慢速强行截割硬度不大的顶板
In order to meet the needs of designers for the selection of fully mechanized mining equipment, the Information Collaboration Group organized a site investigation in 10 units in 1978. After that, we also learned and analyzed some domestic and foreign materials.This article focuses on the coal mining machine, Shifting bracket and scraper conveyor selection I. Shearer: Full-mechanized mining face coal mining machinery is mainly drum units and plows. Roller unit: Its role is to break coal and coal. Fixed drum The coal machine has the advantages of simple structure, convenient maintenance, no rocking arm and small machine width. The rocker arm drum shearer can be adjusted to adopt a high adaptability and is currently used more. The main aspects of choosing a coal winning unit are the following aspects: 1) has a powerful enough power, can be used in a variety of hardness and rock with a clip of the coal; in the local geological changes in the zone can slow forcibly cut less hard roof
