梅州抽水蓄能电站二期工程位于广东省梅州市五华县境内，电站总装机容量120万千瓦，安装4台30万千瓦机组，总投资约47亿元,该电站服务粤港澳大湾区新型电力系统构建，助力广东新增的2000万千瓦风电、2000万千瓦光伏稳定接入南方电网。

北京中煤在项目实施过程中坚持技术引领，系统谋划整体工艺、装备及钻具组合，克服了岩层硬度高、断层多等难题，确保了施工的顺利进行。在定向导孔过程中应用了“定向钻+磁对接技术”，融合了随钻测斜纠偏系统、磁盘定点导向系统的优势，使得“水电系统长竖井定向导孔井偏精度问题”得以攻破，反井扩孔采用BMC600反井钻机一扩成井，完全取消了炸药的使用，加快了工期，提高了井筒施工安全性，赢得了业内充分肯定。

The second phase of Meizhou Pumped Storage Power Station is located in Wuhua County, Meizhou City, Guangdong Province, with a total installed capacity of 1.2 million kilowatts and four 300,000 kilowatt units, with a total investment of about 4.7 billion yuan. The power station serves the construction of a new power system in the Guangdong-Hong Kong-Macao Greater Bay Area, and helps Guangdong's new 20 million kilowatts of wind power and 20 million kilowatts of photovoltaic power to connect to the Southern Power Grid.

In the process of project implementation, Beijing China Coal adhered to the technical guidance, systematically planned the overall process, equipment and drilling assembly, overcame the difficulties of high rock hardness and multiple faults, and ensured the smooth progress of construction. In the process of determining pilot holes, "directional drilling + magnetic docking technology" is applied, which combines the advantages of inclination-correction system while drilling and disk fixed-point guidance system, so that the "wellbore deviation accuracy problem of long vertical shaft fixing pilot holes in hydropower system" can be solved. The BMC600 reverse drilling rig is used to expand the borehole into a well, completely eliminating the use of explosives and speeding up the construction period. It has improved the safety of wellbore construction and won full recognition from the industry.
