最近,江苏南风化工有限责任公司13号井与11号、12号井在地下2664米处实现连通对流.穿透芒硝主矿层厚度13米,水平段长310米,开创了我国三井水平连通开采深层芒硝的先例,标志着我国深井水溶开采芒硝达到了新水平.
Recently, No. 13 well of Jiangsu Nanfeng Chemical Co., Ltd. and No. 11 and No. 12 have achieved convection at 2664 meters underground. The thickness of the main ore-burrow layer is 13 meters and the horizontal section is 310 meters. It has created a horizontal continuous mining of Mitsui in China. The precedent of deep Glauber’s salt marked a new level of water soluble mining of Glauber salt in China’s deep wells.
