折叠、悬挂式挡煤板在复采煤层炮采工作面的应用

Application of Spillplate in The Way of "Folding,Hanging" at Blasting Mining Working Face in Compound Mining Coal Seam

为了使资源枯竭矿井做到原煤的精采细收,通过对复采煤层炮采工作面挡装工序进行深入研究探索,设计了折叠、悬挂式挡煤板。介绍了挡煤板的工艺结构、操作方法,并提出了安全可靠的实施步骤,确保了矿井的安全生产和煤炭资源的精采细收。

In order to mine residual coal seam completely in the mine with rare resource,new spillplate in the way of ＂folding,hanging＂ was designed by researching spillplate processes deeply at blasting mining working face in residual coal seam. The article introduced technological structure and operation method of spillplate,proposed implementing steps which are reliable and safe. Application of this kind of new spillplate ensured the safety production and residual coal seam mining completely in the mine with rare resource.
