On September 16, 2006, the world's first underground drilling and drilling machine and the world's first tunneling robot using flying missile navigation technology were successfully developed on the same day of Sany Heavy Equipment; on September 18 of the same year, the first domestic company The mining machine EBH340 was successfully launched in Sany Heavy Equipment. This series of "firsts" made the industry look at the Sany reloading.
The world's first large slope boring machine
On April 25, 2007, in the main inclined shaft of the Hunchun Banshi coal mine in Jilin with a slope of 25 degrees and a footage of about 1000 meters, it was from Hegang Coal, Huaibei Mining, Shenyang Coal, Jinniu Energy, Shanxi and other coal groups. Dozens of experts in the coal industry are eager to inspect a roadheader that looks different from conventional products.
The crawler claw of this roadheader firmly grips the very steep ground. The first transporter is longer than the conventional one. There are also one cylinder on each side of the rear of the machine. The cutting head cuts the rock flexibly and freely. There is no need to shift when positioning the cut. This is the EBZ160 (CD) large grade roadheader developed and manufactured by Shenyang Sany Heavy Equipment. It has been working in Banshi Coal Mine for 4 months.
Sun Jingchun, deputy mine manager of Banshi Coal Mine, said that the steep slope boring machine entered the scene in December 2006 and has now accumulated a total footage of 730 meters. According to this efficiency, Banshi Coal Mine is expected to be put into operation in August this year, ahead of the expected construction period. 16 months.
Banshi Mine is the key project of Jilin Province during the “Eleventh Five-Year Plan†with a total investment of 510 million yuan and a production capacity of 900,000 tons. As a shallow coal seam, it is designed as a main inclined shaft and digs downwards. On a 25-degree slope, it is necessary to dig 250 meters. Conventional roadheader, the parameter stipulates that its maximum climbing ability is 16 degrees. In fact, it is very difficult to carry out the process of cutting and receiving materials on the slope above 10 degrees. At present, there is no such steep slope in the world. The precedent for excavation.
Liang Jianyi, dean of the Shenyang Research Institute, said at the scene that rock tunneling has always been a worldwide problem, especially the development of large slopes. During the use of the equipment, some faults will inevitably occur, such as large slope retreat, crawler grip and rear support and body connection. Now the Sany Heavy Equipment has been improved for the second and third large slope boring machines produced by Hunchun Mining. The main focus is on the use of high teeth to strengthen the track shoes to improve and solve the crawling problems of the tracks; further increase the loading Star wheel's aggregate capacity to improve the efficiency of collection and transportation; high reliability internal spray sealing structure to prevent early failure; improve the ability to retreat.
Safe, reliable, efficient and humanized is the product design concept that Sany Heavy Equipment has always followed. The steep slope boring machine has made major technical improvements on the basis of the traditional EBZ160 roadheader, applying 10 patented technologies.
The leader of domestic excavation technology
What makes Sany Heavy Equipment the leader of domestic tunneling technology? The concept of “Quality changes the worldâ€, “everything stems from innovation†and the work style of “slowness and enmity†make Sany Heavy Equipment a rising star in the coal mining industry.
At the beginning of the reorganization of Sany in 2004, the company's development goal was locked in the development and manufacture of coal mining equipment. General Manager Wu Jialiang said that revitalizing the old industrial base and the country's accelerated energy construction provided a double opportunity for Sany Heavy Equipment.
The “Eleventh Five-Year†development plan for the coal industry clearly states that by 2010, the mechanization of large and medium-sized coal mines nationwide will reach 95% and 80% respectively. However, the grim reality is that the degree of mechanization of coal mining in state-owned key coal mines is 77.78%, the mechanization degree of integrated coal mining is less than 63%; the mechanization degree of excavation is 23%, and the degree of mechanization of integrated excavation (anchor, excavation, drilling) Only 18.03%, compared with the developed countries, the indicators are 10 to 15 years behind.
Wu Jialiang said that it is committed to the localization of complete sets of coal mining equipment. This is the original intention of Sany Heavy Equipment's high starting point to intervene in coal mining machinery manufacturing.
At the beginning of its establishment, Sany Heavy Equipment quickly established its own technology leapfrog, established the largest research institution in the industry with 100 professional R&D personnel, and built the first EBZ160 roadheader in the year of the company's establishment. In the month, the first high-power hard rock roadheader EBZ200H in China was successfully developed. In September 2006, the world's first underground drilling and drilling machine and the tunneling robot using the navigation missile navigation technology were successfully developed, and the Sany reloading was put on the commanding heights of the domestic excavation technology. In the Wuhan-Guangzhou Railway, in the Liuyang section of Changsha, the first domestic tunnel boring machine produced by Sany Heavy Equipment has shown the elegance of the pilots.
Up to now, Sany Heavy Equipment has applied for 31 patents, obtained 10 patent certificates, and obtained 8 coal safety certifications and 4 explosion-proof certificates.
"We have to use 3 to 5 years to shorten the gap with foreign countries for 10 to 15 years, and build Sany Heavy Equipment into a domestic first-class coal mining production base." Wu Jialiang said.
Shenyang Sany Heavy Equipment Launches World's First Large Slope Boring Machine
The first China Coal Industry Mechanization Development Forum, this conference with important influence throughout the country was held in Shenyang Sany Heavy Equipment Co., Ltd. for one reason: the company's independent innovation performance is outstanding.
