As early as 2,700 years ago, the ancients mastered the complete underground mining technology

The Yangtze River Daily Da Wuhan Client August 20th (Trainee reporter Bao Meng) "In order to ensure the normal operation and operation of underground mining, the ancient ancestors had mastered the complete underground mining technology more than 2700 years ago." August 15th In the afternoon of the afternoon, the members of the Wuhan Metropolitan Circle Explanation Group of the Wuhan Metropolitan Circle of the Wuhan Metropolitan Mine Line in the Tonglu Mountain Mine site were learned from the Yangtze River. Shock.

The members of the visiting regiment came to an underground mining site by the lobby of the huge malachite. "Now we are visiting the Mine -1 mining place of the Spring and Autumn Period 1 of Tonglu Mountain No. 7. This is the longest and largest underground mining site in the world. The scene of mining ore, the current site we see is to peel off the ancient surface wells at an altitude of 91.9 meters to 54.3 meters.

"The ancients used tenon -and -mortise support structures to ensure underground construction safety"

"There are many kinds of wooden structural frameworks in the site. What is this used for?" Asked the visiting group member and Wuhan citizen Zhou Lihua.

"This is the tenon -and -mortise support technology invented by ancient craftsmen to support the lane and ensure the stability and safety of the underground space structure. Some wells we currently see in the site are early to the Western Zhou Dynasty." Li Mei said.

"How did the ancients install it? Is the size and installation of these wooden frames particular about?" Zhong Ying, a member of the Visiting Regiment and the Broadcast of the School of Journalism and Information Communication of Huazhong University of Science and Technology, then asked.

"From the stenosis of the bracket, it can be seen that the support should be installed while the ancients were installed and installed. The framework was generally installed every 40cm." Well Lane. "It can be seen through observation that the lane roads are very narrow, and only one person can enter at a time, so the size of the framework is also very particular. After measuring, it is found that the tenon is usually made of round wood for about 6 cm. The round wood is cut, and the arrow wedges are cut off at both ends to prevent the well frame from falling. "Li Mei said.

"Living bamboo manufacturing high and low air pressure deviations to complete natural ventilation"

"In addition to supporting, the most important thing for mining under the well is ventilation and drainage, and the ancient craftsmen had solved these technical problems as early as 2000 years ago." Li Mei said.

"It is speculated that according to the underground wind wall relics, the ancients completed natural ventilation according to the mountains by the mountain according to the mountains. The bamboo slices with low burning points and low smoke will be ignited on a cloudy day to heat up the air in the well. The air is swap outside. In addition, although the ruins we are currently seeing are dry, in fact, the groundwater level of the ancient copper green mountains is high and the rainfall is large. Most of the ancient ores are lower than the diving position 20 meters. In order to ensure the normal work of the work, it also invented the drainage of the sink and ditch. "The invitation experts invited by the interview group who personally participated in the archeological work of the Tonglu Mountain Mine site, the researcher at the Hubei Provincial Cultural Relics and Archeology Research Institute, and the Hubei Institute of Technology in the middle reaches of the Yangtze River Mineral Mineral Minerian culture and the economy and society. Chen Shuxiang, a professor at the Development Research Center, introduced to the members of the visiting group.

"There is no large area of ​​landslide accidents in ancient mines"

"In the early spring and autumn of more than 2,700 years, it was better to solve technical problems such as underground mining tracing ore, well -lane support, ventilation, drainage, lighting, and improvement. No corpses were found in the ancient ore we currently discovered. There is no large area of ​​landslide accidents. "Chen Shuxiang said.

Chen Shuxiang introduced that we found a large number of tombs different times at the Tonglu Mountain Mine site through archeological excavations. Discover 246 tombs during the pre -Qin period, including 1 Xia Dynasty tomb, 2 Shang Dynasty tombs, 13 tombs in the Western Zhou Dynasty, and 10 were tombs of the Qing Dynasty. The key issues of archeology -see things and people. "Chen Shuxiang said that the Copper Green Mountain site is the longest continuation time, the most complete chain, the highest level, the largest scale, and the best preservation. The ancient craftsmen here have made great contributions to the development of Chinese bronze civilization.

"Through this bronze culture traceability, I understand the history of the ancient mining mining in detail, and I also admire the wisdom of the ancients. Zhou Chuyao, a junior of the college's network and new media major.
