1982年6月14日12时,利用湘乡县省水泥厂万罗山矿区人工爆破,对地下水,土地电进行了一次爆破效应的观测试验,试验从3月5日开始,6月19日结束。 一、基本情况 交通位置 万罗山位于湖南省湘乡县棋子桥公社,地理坐标东经112°11′45″,北纬27°45′45″,爆破碉室坑道底板海拔320公尺,试验场距湘黔铁路棋子桥站3公里。 人工爆破试验概况这次爆破系采矿扩邦工程,爆破场自然条件两面临空,两端夹制,属于多自由面,爆破主碉长33米,1号支碉长20米,2号支碉长11米,两个药室总装炸药量89.53吨。导碉堵塞长度26米,爆破能量相当于M_32.6级地震。
At 12 o’clock on the June 14, 1982, using the artificial blasting at the Wanluoshan mining area in the cement plant of Xiangxiang County, a blasting effect experiment was conducted on groundwater and land electricity. The experiment started on March 5 and ended on June 19 . I. Basic Information Traffic Location Wanluo Mountain is located in Qixizha commune, Xiangxiang County, Hunan Province. The geographical coordinates are 112 ° 11’45 “east longitude and 27 ° 45’45” north latitude. The floor of blasting tunnel is 320 meters above sea level. The test ground distance Xiangqian Railway Paiziqiao Station 3 km. Artificial blasting test Overview The blasting is a mining expansion project, blasting natural conditions on both sides of the blast, both ends of the folder, are free surface, blasting the main tower length of 33 meters, No. 1 branch tower 20 meters long, No. 2 branch towers 11 meters long, 89.53 tons of explosives in two medicine rooms. Tower blockage plugging length of 26 meters, the blast energy equivalent to M_32.6 earthquake.
