随着综采设备在煤矿越来越多地使用,支架的下井问题已为人们所十分关注。就目前支架单重来说,每架重量大都在7～12t左右,而一般设计能力100万t左右的矿井,立井大都安装滚筒直径3m或4m绞车,若要整体下放支架,绞车能力是不适应的,安全上也有较多的问题。下面就我矿利用原有设备稍加改造使整体支架安全下放一事作详细介绍。 With the increasing use of fully mechanized mining equipment in coal mines, the problem of well support has been paid much attention to by people. For the current stand-alone weight, the weight of each frame is about 7 ~ 12t, while the general design capacity of 1 million t mines, shaft most of the installation drum diameter 3m or 4m winch, to the overall decentralized stent, winch capacity is not adapted There are also more problems with safety. The following mine on the original use of the original equipment slightly modified so that the overall decentralization of the stent for a detailed description.
