综放工作面煤炭回收率低，不仅是对煤炭资源的浪费，而且对矿井的安全生产带来一系列不利因素。如：加剧矿井采掘接续紧张的矛盾；采空区残留煤体会产生应力集中，不利于顶板管理；采空区内残留煤体较多，容易引起煤体的自燃发火等。因此，提高综放工作面煤炭资源回采率对增加工作面产量、降低煤炭自燃发火条件、保护煤炭资源有着重要的意义。
綜放工作麵煤炭迴收率低，不僅是對煤炭資源的浪費，而且對礦井的安全生產帶來一繫列不利因素。如：加劇礦井採掘接續緊張的矛盾；採空區殘留煤體會產生應力集中，不利于頂闆管理；採空區內殘留煤體較多，容易引起煤體的自燃髮火等。因此，提高綜放工作麵煤炭資源迴採率對增加工作麵產量、降低煤炭自燃髮火條件、保護煤炭資源有著重要的意義。

The coal recovery rate of fully mechanized working face is low, which is not only a waste of coal resources, but also brings series of adverse factors for mine safety in production such as: aggravating the contradiction of continue strain of coal mining; the residual coal in goaf will produce stress concentration which goes against roof management; the residual coal in goaf is much, which will cause spontaneous combustion of coal easily, etc. Therefore, improving the recovery rate of coal resources at fully mechanized working face has important significance in increasing the output of working face, reducing the conditions of coal spontaneous combustion, and protecting the coal resources.
