Sibaitang (Henan Provincial Nonferrous Metals Geology and Minerals Bureau) searches for large and good mines for the country, which is the basic responsibility and the basis for survival of geological exploration units; developing mining and taking the road of integrated exploration and mining is the new situation.

The direction to enhance the strength of geological prospecting units; prospecting engineering is not only an indispensable method for geological prospecting, but also an important means to obtain economic benefits and improve comprehensive competitiveness.

In the development goals formulated by our bureau to "highlight the main business, expand industry, develop auxiliary industries, and enrich the family business", exploration technologies such as drilling and pit exploration are included in the auxiliary industries. Now the status of drilling in on-site exploration units,

The function and deep hole drilling construction technology and management are briefly discussed for discussion with everyone.

1. The role of drilling engineering in geological prospecting. As a geological exploration unit, geological work is the core. Geophysics, geochemistry, remote sensing, surveying, trench well surface exploration, etc. are indispensable methods and means for preliminary geological work.

When the local, physical, chemical and remote work reaches a certain level, drilling verification will begin to control the size, shape and thickness of the ore body. At the same time, the rock ore core will be taken out and submitted to the laboratory for determination of the ore grade. The geophysical detection well will also obtain numerous

geological information.

At this stage, when geophysical and other methods and means cannot accurately control the spatial location and ore grade of ore bodies, drilling engineering is an indispensable and important means for deep ore prospecting.

It is well known that drilling is an important means of prospecting. The discovery of 100 large and extra-large mineral deposits in foreign countries introduced in the book "Information Prospecting Strategy and 100 Examples of Exploration" is inseparable from drilling.

Australia's Olympic Dam copper-gold-uranium deposit, which began geological work in 1957, made a major breakthrough after systematic control of drilling engineering began in 1975, making the mine the largest uranium deposit and the sixth-largest copper deposit in the world.

In the exploration of mineral resources in countries such as Australia, South Africa, Canada, and the United States, pit exploration work is rarely used in preliminary exploration, and deep verification is mainly based on drilling work.

my country's famous Bayan Obo mining area, the molybdenum ore fields, coal fields and numerous bauxite mining areas in Henan Province were all proven to have high-level reserves after using extensive drilling projects.

In the past, drilling played an important role in geological exploration. At present, in the exploration of "exploring depth to find blind spots and exploring edges to find out the bottom", drilling is a necessary method for geological prospecting. Therefore, it is particularly important to improve the level of drilling technology and equipment and the quality of employees.

important.

2. Drilling projects are an important means to expand economic scale and obtain economic benefits. In recent years, our Bureau has undertaken many government and social geological exploration projects every year, and the annual geological project design drilling workload is about 70,000 to 80,000 m.

According to the statistics of our Bureau in 1979, 28 drilling rigs were operated that year, and a drilling volume of 69,997m was completed in 16 mining areas. There were about 1,000 drilling technical workers and service personnel.

Drilling work not only serves geological prospecting, but also places a large number of employees, maintaining the stability of the team and the continuation and development of drilling technology.

The depression in geological work during the "Ninth Five-Year Plan" period caused a sharp reduction in drilling workload. In the past five years, a total of 10,722m of planned drilling work was completed. A large number of equipment was idle or repurposed for other purposes, personnel were diverted and laid off, and technical equipment was severely weakened.

In the past four years, our province has used the "Two Rights Price" project fund to inject a large amount of funds into the equipment update of geological exploration units. The drilling equipment of our bureau has been strengthened accordingly. Currently, there are more than 30 sets of core drilling equipment in full production.

According to the scale of the existing equipment, after proper organization, the drilling workload can be completed every year about 100,000 m.

In 2008, the designed drilling workload in our bureau’s planned and social geological projects was 130,000 m. If all the drilling work was carried out by our bureau’s drilling team, the output value would be approximately 50 million yuan. In terms of personnel placement, team training, improvement of drilling technology level, and acquisition of

Economic benefits and other aspects will play a greater role.

The Henan Provincial Coalfield Geology Bureau has 5 units with drilling construction capabilities. There are about 150 sets of drilling rigs with a drilling depth of more than 1000m, forming a strong production capacity. Large-diameter, ultra-deep coal mine ventilation, dewatering, ice delivery holes, coal bed methane

Horizontal drilling construction technology has reached the national advanced level.

In recent years, he has been engaged in drilling work in coalfield geology, coalbed methane, shallow oil, oil shale, coal mine ventilation and dewatering holes in 8 provinces (regions) including Henan, Xinjiang, Shaanxi, Shanxi, Inner Mongolia, Jilin, Guizhou, and Yunnan.

The drilling workload is about 700,000 to 1 million m, and the annual output value is 300 million to 400 million yuan. It not only places a large number of employees and improves the level of drilling technology, but also obtains significant economic benefits.

The Second Coalfield Geology Team used the drilling income to renovate the old base and build the employee residential area into a national civilized community.

The Fourth Coalfield Geology Team used the drilling income to invest 15 million yuan to complete the waterway renovation and install gas and heating in the Pingdingshan employee residential area. The quality of life of the employees has been improved.

The successful experiences of many domestic drilling companies and geological teams in drilling construction are worthy of our careful study and reference. Their practice has proved that the drilling equipment and drilling technical workers of geological exploration units are not a burden. The drilling construction industry not only provides guarantee for geological prospecting

, and can place employees and maintain team stability. More importantly, it can enhance the unit's comprehensive competitiveness, improve the unit's visibility, and obtain huge economic benefits from drilling construction.

3. Deep hole drilling technology, equipment and construction technology The non-ferrous metal geological exploration team has its own characteristics and has accumulated rich experience in the exploration of endogenous metal deposits.
