一般所谓“南方小型煤矿”,实际上是指我国东南地区(即:浙、闽、赣、湘、鄂、粤、桂七省和苏南、皖南及黔东南地区)的那些小型煤田。由于这些煤产地的地质条件比较复杂,含煤地层连续分布的面积较小和煤层较薄,因而通常只能建设小型矿井。近年来,煤田勘探和矿井建设工作的实践表明:为查明这些小型煤矿的资源和矿山开采技术条件,除了在勘探方法上应遵循一些对所有煤田都有普遍指导意义的技术原则以外,还必须采取若干
The so-called “small coal mines in the south” actually refer to those small-scale coal fields in the southeast region of China (ie, Zhejiang, Fujian, Jiangxi, Hunan, Hubei, Guangdong and Guangxi provinces and southern Jiangsu, southern Anhui and Qiandongnan). Due to the complex geological conditions of these coal-producing areas, small continuous coal-bearing strata and thin coal seams, small-scale mines are generally only constructed. In recent years, the practice of coalfield exploration and mine construction work has shown that in order to identify the resources and technical conditions for mining these small coal mines, in addition to the exploration of some of the technical principles that are of general guiding significance to all coalfields, Take a few
