利用钻孔从地下开采自然硫磺矿在我国还处于试验阶段。它是采用向孔内注水压裂矿层，通过高温热液把胶态或晶质的自然硫熔为硫液，然后用气举方法采至地面。我队从1981年参与钻孔施工，至今已有五个钻孔从孔内压通，经注冷水试验，进水量已达到采硫要求，现有四个孔安装了井下采硫装置和井口采硫树等设施，与国外技术合作正式投入采硫试验。国内外经验表明，用钻孔开采某些液态和可熔性矿产资源，具有工期短、经济、安全等优越性。具体表现为：1．探采结合；2．能够开发矿层多、品位低、深度大、水文地质条件复杂，矿层在承压水以下的矿床；3．节约了井巷工程和支护、通风、排水、提升等工序设施；4．减少矿山地面设施，如废石堆放和选矿
The use of drilling from the underground exploitation of natural sulfur ore in our country is still in the experimental stage. It is the use of water injection to the hole fracturing seam through high temperature hydrothermal molten or crystalline natural sulfur melt sulfur liquid, and then gas to the ground method. My team has been involved in drilling construction since 1981, so far five holes have been drilled through the hole. After the injection of cold water, the water intake has reached the requirement for sulfur capture. The existing four holes are equipped with underground sulfur extraction facilities and wellhead mining Sulfur and other facilities, with foreign technical cooperation formally put into the sulfur test. Domestic and foreign experience shows that the drilling of certain liquid and fusible mineral resources has the advantages of short construction period, economy and safety. Specific performance: 1. Exploration and mining combination; 2. To develop multi-ore, low grade, large depth, complex hydrogeological conditions, ore deposits below the confined water deposits; 3. Save the tunnel engineering and support, ventilation, drainage, upgrading and other processes and facilities; 4. Reduce mine surface facilities, such as waste rock piles and beneficiation
