为了研究邢台矿综采工作面回采过程中对其正下方40~45 m处野青带式输送机巷的影响,在野青带式输送机巷建立观测站和顶板变形观测点,并对测试数据进行整理分析,结果表明:工作面推进过程中,野青带式输送机巷顶板锚杆受力基本稳定,顶板受力比较均匀,未受到大的地质构造应力和工程应力的影响;顶板呈现先上升后降低的趋势,且离工作面越近,顶板上升量越大,最大上升量约为160 mm。
In order to study the influence of Xingtai mine fully mechanized coal mining face during the mining process on the wild blue belt conveyor lane at 40 ~ 45 m just below Xingtai Mine, observation stations and roof deformation observation points were set up in the wild blue belt conveyor lane. The test data The results showed that during the process of working face advancement, the anchorage force of roof bolt of wild lane belt conveyor was basically stable, and the roof stress was relatively uniform without being influenced by the large geological tectonic stress and engineering stress. The roof showed the first Rise and then decrease, and the closer to the work surface, the greater the amount of roof rise, the maximum increase of about 160 mm.
