VPRS 19348 Brown Coal Investigation, Records of Boring Operations

This series contains records of boring operations carried out by the State Electricity Commission of Victoria (VA 1002) in the parishes of Hazelwood, Loy Yang and Maryvale. The records are copies of original documents of work conducted over the period of approximately 1913-1950, which were later collected and bound into volumes by the Mines Department (VA 612), possibly in the late 1940s – early 1950s. With few economic deposits of black coal found in Victoria, the Mines Department turned to brown coal as a main source of energy for generating power in the early twentieth century, with the Geological Survey of Victoria (VA 4118) playing a key role in the state’s large-scale exploitation of brown coal reserves. While considered the lowest grade of coal, brown coal was found to be abundant especially in the Latrobe Valley and provided a source of energy to developing Victoria. The State Electricity Commission of Victoria held responsibility for the development of the brown coal resources of the State, which in the post-war period of 1945-1950s was struggling. It’s thought that the volumes within this series relate to the Commission’s research into new brown coal resources during this period. Information included in these records includes the parish and specific location of bores, bore number, dates bores were started and completed, depth water was struck, particulars of core (soil, clay, coal, etc.), depth struck and thickness, and final depth of bore. There are also analyses of samples collected during drilling. Records are often signed by the Power Station Superintendent. This information is subject to further research.本系列档案收录了维多利亚州电力委员会（State Electricity Commission of Victoria, VA 1002）在黑泽尔伍德、洛伊扬及玛丽维尔教区开展的钻探作业记录。本记录为1913年至1950年左右期间作业的原始文件副本，后由矿产部（Mines Department, VA 612）于1940年代末至1950年代初收集并装订成册。 鉴于维多利亚州境内探明的经济可采黑煤储量稀缺，矿产部于20世纪初将褐煤作为发电核心能源来源，维多利亚州地质调查局（Geological Survey of Victoria, VA 4118）在该州褐煤储量的大规模开发进程中发挥了关键作用。尽管褐煤被归类为最低品级的煤炭，但其储量极为丰富，尤其在拉特罗布谷分布广泛，为处于发展阶段的维多利亚州提供了可靠的能源保障。 维多利亚州电力委员会负责本州褐煤资源的开发工作，而在1945至1950年代的战后时期，该委员会的开发工作曾陷入困境。据推测，本系列中的档案册与该委员会在此期间针对新褐煤资源开展的勘探研究相关。 本记录包含的信息涵盖：钻探井所属教区及具体点位、钻孔编号、钻孔开工与完工日期、见水深度、岩芯详情（土壤、黏土、煤炭等类别）、见岩深度与厚度，以及钻孔最终深度。此外还包含钻探过程中采集的岩样分析报告。此类记录通常由电站主管签字确认。 本档案所涉信息仍有待进一步研究考证。
