为了满足我国煤炭生产日益发展的需要,克服以往沿空留巷技术存在的不足和弊端,针对沿空留巷需经两次采动影响,矿压显现强烈,顶底板及两帮移近量大等特点,我们与中国矿大北京研究生部共同在鹤壁矿务局一矿1807回采工作面下顺槽,采用中国矿大北京研究生部研制的高水固化材料和插底式矿工钢梯形可缩性支架及鹤壁矿务局研制的套装式矿工钢梯形双向可缩性支架作为巷旁支护材料和巷内支护材料,进行了高水固化材料巷旁泵充填沿空留巷新技术的工业性试验。1807工作面下顺槽充填工作于1990年12月24日起到1991年8月底结束,共充填395m。该地区由于受向斜轴的影响,1807工作面下顺槽留巷后仍作为下区段1808工作面的下顺槽使用。从1991年9月5日1808工作面回采开始,截止到1991年11月10日,已沿走向推进95m,留巷经两次采动影响,状况
In order to meet the needs of the growing coal production in our country, overcoming the shortcomings and shortcomings of the past gob-side entry retaining technology, Etc., we co-operate with China University of Mining and Technology Beijing Graduate Department under the 1807 working face of Hebi Mining Bureau No.1 Mine. We adopt the trapezoid retractability of high water solidified material and plugged miners’ steel developed by the Graduate School of Beijing University of Mining and Technology Stent and Hebi Mines developed suitcase miners trapezoidal bidirectional retractable bracket as roadside support material and laneway support materials, carried out high water-cured material laneside pump Filling Gutter new technology industrial test . 1807 Face under the trough filling work December 24, 1990 from the end of August 1991 ended, a total of 395m to fill. Due to the influence of the inclined axis, the area is still used as the lower groove of the 1808 working face of the lower section after retaining the roadway under the groove 1807. From September 5, 1991 1808 face mining began, as of November 10, 1991, has been advancing along the 95m, leaving the lane after two mining influence, the situation
