摘要
为了保证两硬大采高综合机械化采煤工作面安全生产,在掌握采面矿山压力显现规律的基础上,选择ZZ9900/29.5/50支撑掩护式液压支架控制采场顶板,针对两硬特点,8402大采高工作面选择自然垮落结合人工强制放顶技术控制顶板,取得了良好的技术经济效益,为同煤集团公司其它条件类似采面提供了可靠的顶板控制技术和管理经验。
In order to ensure the safe production of two hard large mining height full-machanized mining face, on the basis of having controlled the law of mining face pressure, ZZ9900/29.5/50 shield hydraulic support was used to control the roof. Due to the two hard characteristics, natural caving, combined with artificial forced caving technology was chosen to control the roof of 8402 large mining height mining face. These measures abtained good technical and economic benefit and provided similiar mining face of Datong Coal Mine Group Company with reliable roof control technology and management experience.
