坚硬顶板薄煤层皮带巷洁净快速施工技术

Clean and Fast Construction Technology for Strap-laneway of Thin Coal Bed with Hard Upper Plank

我国煤炭开采中薄煤层比例占50%以上,传统的施工方法矸石量大,处理困难,为改变这一现状,新汶矿业集团汶南煤矿在坚硬顶板煤层皮带巷施工中,通过选取合理的断面形式,改进施工工艺,不但实现了洁净生产,而且加快了掘进速度,开创了一套薄煤层巷道掘进的新工艺。

In China, thin coal beds exceed 50% of whole mining coal. With traditional construction method, the waste of coal mine is very huge and it is difficult to process. In order to change this actuality, Wennan Coal Mine of Xinwen Mining Corporation improves construction technology hy selecting the reasonable section form in strap- laneway of thin coal bed with hard upper plank. With construction technology, the mine not only has realized the clean production, but also quickenes the excavation speed. And then, a whole new excavation technology for laneway of thin coal bed is created.
