臺東縣溫泉資源豐富,金崙溫泉區具備豐富溫泉資源與廣大腹地,溫泉區劃設完成後,溫泉開發及地熱發電申請案持續增加。在確保溫泉產業能永續利用與經營前提下,建置溫泉監測設施,監控開發行為對溫泉資源影響情形,為保護溫泉資源之重要工作。
監測井設置於金崙紅橋左岸,監測井深度為94公尺,為高溫、高壓、自噴式水井。溫泉泉質pH為8.7,井口溫度為72.1度,泉質屬碳酸氫鈉泉,出水量約0.00146cms。井口閥門開啟後,井內壓力逐漸上升,約30分鐘後成為自噴形式,維持2-3小時後壓力消退,可反覆維持此現象,成為「間歇泉」形式。
由金崙溫泉監測井水位變化曲線顯示,水位位於高程57.45-57.65公尺之間波動,上下幅度僅約20公分。星期一至星期日之間水位並無太大變化,其中以週五最高水位顯示略低,週六與週日最高水位即恢復至57.65公尺位置,顯示金崙溫泉區於假日之溫泉用水量,並無明顯影響水位變化情形。 Taitung Jinlun Hot Spring Area in Taiwan is rich in hot spring resources and vast hinterland. After the hot spring area is completed, the application for hot spring development and geothermal power generation continues to increase. Under the premise of ensuring the sustainable use and operation of the hot spring industry, it is necessary to establish a hot spring monitoring well to monitor the impact of development activities on hot spring resources, and to protect the hot spring resources.
The monitoring well was set on the left bank of Jinlun red bridge. The monitoring well depth is 94 meters, which is high temperature, high pressure and self-injection well. The hot spring pH is 8.7 and water temperature is 72.1 degrees. The water quality is sodium bicarbonate and outflow is 0.00146 cms. After the wellhead valve is opened, the pressure in the well gradually rises and becomes a self-injection after 30 minutes. The pressure is reduced for 2-3 hours, well phenomenon can be maintained repeatedly and become a form of "Geyser".
The water level change curve of the monitoring well in Jinlun Hot Spring shows that the water level fluctuates between 57.45-57.65 meters of elevation, and the upper and lower amplitude is only about 20 cm. There is not much change in water level between Monday and Sunday, with the water level on Friday being slightly lower, and the highest water level on Saturday and Sunday returning to 57.65 meters, indicating the amount of water used in the hot springs in the Jinlun Hot Spring Area. No significant impact on water level changes.
