摘要
3313综采工作面初采阶段为扇形开采,初次放顶期间矿压显现规律与普通综采工作面不同,通过现场详细设点进行矿压观测,掌握了直接顶和老顶初次跨落规律,对类似条件下的扇形开采工作面开采,可以借鉴,提前采取可靠的顶板维护措施,实现安全生产。
3313 fully mechanized face is arranged in sector in the first mining stage,during the first roof caving mine pressure regularity is different with common working face,by setting point in site,master the initial caving law of the immediate roof and the main roof,it offer reference for mining similar conditions of the fan- shaped working face,for adopting reliable roof maintenance measures in advance,to achieve safe production.
