- 摘要:
- 桃园煤矿北八采区在开拓掘进过程中煤系砂岩多处出现涌水现象，且涌水量大、水温高、水质异常。为了判断北八采区砂岩水的水源，对矿井各含水层及北八采区砂岩水进行了系统采样，并对常规水化学指标进行了测试和分析。结果表明：北八采区煤系砂岩水与井田南部采区砂岩水水化学指标存在较大差异，而与奥灰水的水化学指标基本一致，该区“砂岩水”已不具有正常砂岩裂隙水的水质特征，具有奥灰水的水质特征，接受奥灰含水层水的补给。研究成果为该区“砂岩水”的防治提出了可靠的地质依据。
- Abstract:
- There existed phenomena of water inrush in multiple places of sandstone in coal measures of the north eighth mining area in Taoyuan coal mine during caving and digging, the amount of water inrush was large, the temperature of water was high and also the water quality was abnormal. To evaluate the sources of sandstone water in the north eighth mining area, each aquifer of the mine and the sandstone water in the north eighth mining area were systematically sampled, and the conventional hydrochemical indexes were tested and analyzed. The results showed that the hydrochemical indexes of sandstone water in coal measures of the north eighth mining area was quite different from that in southern mining area of the coal mine, however, they were in accordance with the hydrochemical index of Ordovician limestone water. The sandstone in this region had not the characteristics of water quality like normal fracture water of sandstone, and it had the characteristics of water quality in Ordovician limestone, as well as it received the supplement of the water from aquifers in Ordovician limestone. The research results provide a reliable geological basis for the prevention and control of sandstone water in this region.
