新疆准噶尔盆地和焉耆盆地掩盖式煤田的勘查

笔者近几年在地表大多数被第四系、第三系地层覆盖的准噶尔盆地准南煤田乌鲁木齐河东七道湾向斜勘查区，准东煤田卡姆斯特勘查区、巴里坤勘查区和焉耆盆地塔什店煤矿区，进行地质勘查工作，通过分析总结、汲取工作中的经验和教训，总结了在隐伏区找煤的工作方法和思路，用二维地震扫面，确定构造形态和标定目的层层位，施工钻孔进行验证，取得了较好的找煤效果，为今后的地质勘探和煤矿开发提供可以借鉴的经验。

Surveys of Concealed Coalfields of Zhunge'er Basin and Yanqi Basin in Xinjiang

In recent years,the author has been conducting geological surveys to certain areas with earth surfaces mostly covered by the Quaternary and the Tertiary strata in the Zhunge＇ er Basin and the Yangi Basin, including prospective coal fields namely,the syncline area in Qidaowan,Hedong,Urumqi in Southern Zhunge＇ er Basin,the Kamusite area and the Barkol exploration area in Eastern Zhunge＇ er Basin,and the. Tashtemir coalmining area in the Yanqi Basin.Thanks to the analysis and summary concerning the experiences and lessons drawn from the said survey＇ work,relevant methods and ideas for finding coal in the concealed areas are figured out,i.e.,applying the two_dimensional seismic prospecting method to determine the structural morphology and demarcate locations of the layers,and then site drilling for verification thereof, which has definitely improved the efficiency of the coal finding,being worthy referencing for the future geological exploration and development of coal mining.
