综采放顶煤大小工作面对接工程的实践应用

Fully Mechanized Caving Top Coal Big and Small Working Face Docking Project Practical Application

为了使煤矿资源能够得到最大限度地利用,煤矿在生产过程中,要根据遇到的褶曲、断层、陷落柱等各种类型地质构造因素而变更原工作面的设计,根据实际地质构造影响情况,分为小面和大面两种情况,俗称"刀把式"工作面。针对工作面回采至大小面对接处产生的问题,探讨了对接工程中所采取的机尾过渡架的拆除与安装、顶板管理、通风瓦斯管理,组织管理等流程,科学合理的制定施工技术方案,保障顺利安全完成对接工作,为类似情况提供经验借鉴。

In order to maximize the use of coal resources, coal mining in the process of production, according to the fold, fault and collapse column, various types of geological structure factors and changed the original design of working face, according to the practical geological tectonic situation, divided into small and big face two situations, commonly known as ＂knife fantasy＂ face. In view of big and small face jointing problem in the mining face stoping, dismantle and installation of the tail transition frame and roof management, ventilation and gas management, organization and management processes, such as scientific and reasonable construction technology plan formulation were discussed, which guaranteed safe work and provided the experience and reference for mines under similar situation.
