The world's first special tunneling boring machine (TBM) for lengthy and steeply inclined coal mine shafts is developed on August 3, 2015

The world's first special tunneling boring machine (TBM) for lengthy and steeply inclined shaft coal mine shafts was completed on August 3, 2015.

Jointly developed by China Railway Construction Corporation Limited and China Shenhua Group, the TBM has complete proprietary intellectual property rights.

The 238-meter machine has an excavation diameter of 7.62 meters and weighs more than 1,200 tons. It can carry out various missions including excavation, lining, deslagging, transportation, ventilating and draining during inclined shaft engineering.

Its development was the first application of a TBM participating in coal mine shaft engineering and marked China's progress in cooperative innovation in large-scale high-end equipment manufacturing.

Baihetan hydropower plant, to be the world's largest, starts construction on August 3, 2017

Construction of the Baihetan hydropower plant, soon to be the world's largest, started on August 3, 2017.

Contracted by China Gezhouba Group Company LTD., a subsidiary of China Energy Engineering Group Co., Ltd., the station is a ten million kilowatt-level large-scale hydropower plant.

Located at the downstream of the Jinsha River's main stream, the plant has a dam of 289 meters in height and a dam crest of 834 meters.

The gross installed capacity of the station is 16 million kilowatts, now the world's second largest and soon to be its largest after construction is completed.

The station is a milestone of the world's hydropower plant construction and follows the operational launch of the Xiluodu and Xiangjiaba hydroelectric power plants and the approval of the building of the Wudongde Hydropower Plant.

Xingkong-2, China's first waverider hypersonic flight vehicle, succeeds on its trial flight on August 3, 2018

Xingkong-2, China's first self-developed waverider hypersonic flight vehicle, succeeded on its trial flight on August 3, 2018.

Developed by China Aerospace Science and Technology Corporation, Xingkong-2 is intended to provide development and flight testing of the hypersonic velocity scientific research platform and to test air innovative technologies.

Many international technical difficulties in the field were solved in its development, including the first verification and application of flight performance with leading thermal protection technology, engineering of the first waverider aircraft and stability control in hypersonic flight.
