摘要
文章就综采工作面缩采安装时,切眼遭遇极破碎顶板、压力大,随时有冒顶危险现状,及时改变支护方案,科学选取安装新工艺,打破传统综采工作面安装方式,采用倒向下架安装。该工艺解决了特殊条件下安装空间不足和安装时易引发冒顶危险问题,不但减少了费用,而且加快了安装工期,确保特殊条件下设备安装的安全。
During the installation of the equipment applied to the fully mechanized coal mining face,the open-off cut operation had an ultra broken roof,high roof pressure and a danger status of the roof ready to falling.The roof support plan was timely changed,the new installation technique was scientifically selected,the conventional installation method of the fully mechanized coal mining face was broken and the powered support was reversely transported and installed.Thus the installation space insufficient and the danger problems of the roof falling occurred in potential under the special conditions could be solved,not only the cost could be reduced,the installation period could be reduced and the safety of the equipment installation under the special condition could be ensured.
