苏联由于煤层地质条件的多样性,20多年来除了大力发展综合机械化采煤外,同时也努力发展和更新不同品种的支护设备以适应各种煤层晋采工作面的需要。苏联目前有六种系列化的支护设备可供普采选用。它们是:摩擦式金属支柱。单体液压支柱、金属铰接顶梁、摩擦式放顶墩柱、液压放顶支架及摩擦式临时支柱。“卫星”型放顶支架就是液压放顶支架的一种,自1198年由部科技情报所推荐以来(见《煤炭科技动态》81年22期及《河北煤炭》82年第3期),已经引起不少局矿的关注。为了更好地学习和借鉴这些经验为我所用,本文主要就扩大其适用范围作一些讨论,以供参考。
Due to the diversity of geological conditions in the coal seams, the Soviet Union has made great efforts to develop and upgrade different types of support equipment in addition to vigorously developing comprehensive mechanized coal mining in the past 20 years in order to meet the needs of various coal mining faces. The Soviet Union now has six series of support equipment for general mining use. They are: Friction metal props. Single hydraulic props, metal hinged roof beams, friction type top pier column, hydraulic top bracket and friction temporary pillars. The “satellite” type roof caving support is a type of hydraulic roof caving support. Since it was recommended by Ministry of Science and Technology Intelligence in 1198 (see “Science and Technology of Coal”, Volume 81, Issue 81 of “Coal Science and Technology”, and " Caused a lot of bureau mining concerns. In order to better learn and learn from these experiences for my use, this article mainly to expand its scope of application for some discussion for reference.
