Rock drilling technology is the forerunner of the extractive industry. my country is the country that invented gunpowder and percussion drilling technology ("Drill"), and has written the glorious history of human percussion drilling technology. Modern rock drilling and blasting technology and rock drilling equipment have become the main means for mankind to obtain resources from the lithosphere and open up space for survival and development underground. The construction of my country's rock drilling technology and rock drilling equipment industry started from the study of Soviet technology after the founding of New China. At present, my country's brazing tools, rock drilling machinery, and cemented carbide industries have many innovative technologies, and many products can compete with similar products from world-famous companies. The "bottleneck" of long drilling tools such as full-face tunnel boring machines (TBM), full hydraulic rock drilling rigs, and heavy-duty drill rods for drilling rigs and cemented carbide monolithic drill rods that we have faced for a long time has been or is about to achieve important breakthrough. This article briefly reviews the modern development process of my country's rock drilling technology and rock drilling equipment industry over the past sixty years.

Rock drilling tools and human civilization open up the world, and the rise and fall of the fish and dragons. From ape to man, labor creates the world. Engels said: Because apes learn to use tools to work, they gradually break away from reptiles and evolve into upright walking people with developed brains. Marx said: "Science is the revolution of the highest significance." Productivity is the most active factor in social progress. All changes in production relations are designed to adapt to the development of productive forces. "Productivity = People + Tools". The stages of human history are marked by the condition of tools. The development history of human society can also be said to be the evolutionary history of tools. The degree of progress of the tool directly shows the level of social development. In the long history of mankind's request from nature, rock drilling tools have been accompanied by the great struggle of people to develop resources and conquer rocks from beginning to end. "Dayu controlled the water, Xi Zhong built a car, and Boyi drilled a well." With wells, mankind can stay away from rivers and lakes and thrive in the depths of the vast land. 4,000 years ago, Boyi was the inventor of percussion sinking in China or the world. After a long period of development and evolution, China's percussion sinking technology has formed the world-famous "burst drilling" technology. On the eve of the Opium War, almost at the same time as Nobel and his sons were developing industrial explosives. In 1835, salt craftsmen in Zigong, Sichuan, China, used "Drill" to drill the world's first ultra-thousand-meter deep well (Zigong Shen?? 1001.42m, for National Key Protected Cultural Relics).

After the Chinese percussion sinking technique flowed into the West through missionaries, the drilling and extraction of oil played a very important role in promoting the progress of human civilization. In some American oil drilling engineering monographs, the beginning is a drawing of a Chinese artesian well worker. In the well-known drilling textbook of the University of Krausstyre in Germany, the first chapter introduces the sinking technology of artesian wells in China. It can be seen that China's percussion sinking technique is actually the pioneer of the world's drilling engineering and has been recognized by the world.

In view of the huge and far-reaching impact of percussion sinking on the development of Chinese civilization and the world, scientists from the Chinese Academy of Engineering Liu Guangzhi, Zhu Guangya and other scientists put forward a point of view, suggesting that it be listed as the "fifth invention of ancient Chinese science and technology", and has obtained numerous The recognition of scientists at home and abroad. The two great inventions have changed the world. "Workers must first sharpen their tools if they want to do well." In the middle of the 18th century, following the British Industrial Revolution marked by the invention of the flying shuttle by Kay and the invention of the steam engine by Watt, after nearly 100 years of relatively slow development into the mid-19th century, the world ushered in two other great inventors, Nobel and his son. . The Nobel father and son grew up in Sweden where metallurgy and mining technology is at the peak of the world. They timely grasped the important and difficult rock-breaking issues that needed to be solved urgently in mining and production. They did not hesitate to shed blood and sacrifice, and continued with the life-long energy and pursuit of two generations. After the Chinese gunpowder, they found more powerful new materials and new energy industrial explosives (the explosives made by nitroglycerin absorbed diatomaceous earth) (1866). In February 1868, the Swedish Academy of Sciences awarded the Nobel Father and Son Gold Medal to reward the old Nobel for his long-term efforts in the development of nitroglycerin explosives; it rewards Nobel's invention of the explosive.

After the 1870s, Nobel operated explosives factories in 20 countries in Europe and the United States. Since then, large-scale mining and road construction projects have begun, which triggered the "real industrial revolution" that led to the rapid growth of social wealth. After industrial explosives were invented, the more urgent and important problem faced by mining engineering is how to efficiently drill holes in rock ores. Since ancient times, the myths of "Pangu Pidi", "Nuwa Refining Stones", "Yu Chiseling the Dragon Gate", and "Foolish Father Moving Mountains" are fascinating. "Shibengshan destroyed the heroes and died, and then the ladders were connected to the stone stacks" Li Bai sighed, "The road to Shu is difficult, and it is difficult to go to the blue sky"! The problem of efficient rock drilling has been plagued by humans for thousands of years. In 1896, the first pneumatic rock drill was born in the United States; in 1900, Sweden began mass production of hollow drill steel for rock drilling. Following Nobel in the early 20th century, the world ushered in a great inventor. He was the German scientist K Schluttel who invented tungsten-cobalt cemented carbide (WC-Co) in 1923. After the invention of WC-Co cemented carbide, a global emerging industry of cemented carbide cutting tools and cemented carbide rock drilling tools has rapidly formed, which has increased the efficiency of mechanical cutting and rock drilling by hundreds of times, and is known as the "industrial the teeth of".

The machinery industry is the heart of modern industry, and the mining industry is the foundation of the entire industry. The invention of cemented carbide made industrial explosives even more powerful. The two major inventions of industrial explosives and cemented carbide have greatly increased the ability of mankind to conquer nature, accelerated the development of transportation, energy, resource development, and the development of basic industries such as metallurgy, machinery, electronics, chemicals, and construction, and promoted nuclear energy, computers, and aerospace. The rise of high-tech industries.
