地压工作是贯彻伟大领袖毛主席关于“开发矿业”号召的一个不可忽视的方面,是实现劳动保护和保证矿山持续安全生产的关键性工作之一。我国冶金老矿山较多,过去反动统治阶级勾结帝国主义,采取挖富弃贫、只采不充的掠夺式开采方式,形成了大量不明空区,遗留隐患。解放后,对老矿不断进行改造和扩建,并建成大量新矿,为矿山安全生产创造了条件。但是,随着时间、空间的进展,对于矿山生产可能发生的地压活动认识不足, Ground pressure is a great leader Mao Zedong on the “development of mining ” call a can not be ignored, is to achieve labor protection and to ensure sustained and safe mine production, one of the key tasks. There are many old metallurgical mines in our country. In the past, the reactionary ruling classes colluded with imperialism and adopted a predatory mining method of dredging the rich and abandoning the poor and using only inadequate means. As a result, a large number of unidentified areas were left behind, leaving hidden dangers. After the liberation, the ongoing transformation and expansion of the old mines, and the completion of a large number of new mines, created the conditions for mine safety in production. However, with the progress of space and time, there is not enough understanding of the underground pressure activities that may occur in mine production.
