近日,重庆市在綦江大罗井田开展煤炭资源普查项目时发现一煤层总厚度为8 m,预计可探获煤炭资源储量为2.13亿t的大型矿区。这是该市近2年在探获綦江小鱼沱、合川盐井等大型煤矿床之后,地质找矿的又一重要突破。大罗井田煤炭资源普查项目是市国土房管局确定的市级地质矿产勘查项目,在2007年12月由重庆一三六地质队竞标承担。钻探工作克服井内垮塌、埋钻等困难,已竣工1个钻孔,正施工1个钻孔,完成钻探进尺
Recently, Chongqing Municipality has discovered a coal mine with a total thickness of 8 m when it conducts a census of coal resources in the large Luo field in Jujiang. It is estimated that a large-scale mining area with a coal reserve of 213 million t can be explored. This is another important breakthrough in the geological prospecting after the city has explored large-scale coal deposits such as the Xiaoyutuo in the Yongjiang River and salt wells in Hechuan in the past two years. Dalai Minefield coal resources census project is the municipal land and the Bureau of municipal geological mineral exploration projects identified in December 2007 by the Chongqing 136 team bidding. Drilling work to overcome the collapse of the well, buried drilling and other difficulties, has completed a drilling, construction is a drill, completed drilling footage
