[本刊讯]2014年11月21日,中国地调局勘探所在河南安棚天然碱矿实施的一对水平对接井在水平井井深3240m处实现了对接连通。这是勘探所继在湖北沙隆达盐矿连通2800m深井后又一新突破,创水平对接井深新记录。河南安棚天然碱矿是国内发现的大型天然碱矿之一,是世界上埋藏最深的天然碱矿床。勘探所实施的水平井开采的矿层埋深达2800m以上,该矿层是由厚度从0.1~1m不等的矿互层及夹层组成,矿 On November 21, 2014, a pair of horizontal docking wells implemented by the Geological Exploration Mine in Anpeng, Henan Province, China, were docked at a depth of 3240m in horizontal wells. This is a new record after the exploration succeeds another 2800m deep well in Sanonda Salt Lake, Hubei Province. Henan Anpeng Trona Mine is one of the largest trona ore found in China and the deepest trona deposit in the world. The horizontal wells drilled by exploration have a depth of more than 2800 m. The mine is composed of interbedded layers and intercalations with thicknesses ranging from 0.1 to 1 m.
