High quality of mining operations and compliance with construction deadlines

Back in 2021, we decided to gradually introduce Chinese-made self-propelled mining equipment into the local tunneling complexes of the Artemyevskaya mine, Maleevsky and Ridder-Sokolny mines. To do this, in November 2021, the chief engineer and site managers were tasked to analyze the dependence of the rate of penetration on the performance indicators of the precinct tunneling complexes and determine the expected effective useful life; each unit, to assess operational productivity based on production factors and mining and geological conditions of the mine (mine, deposit).

The two-year functional diagnostics of the technical condition of the main components and aggregates of Chinese-made mining equipment during its targeted operation in a given period of time was based on such criteria as: the natural operating environment at the field; the coefficient of the aggregate state of the equipment according to the conditions of the field; the duration of use, taking into account the coefficient of the aggregate state, which allowed to establish its potential operability and service life up to  major repairs or write-offs as they wear out completely. The mechanical services of the sites for two years have monitored the parameters of the functioning of the Chinese-made machine in the sinking technology and compared the actual values obtained with the factory recommendations for service life, which are necessary to predict the service life of the equipment introduced into the technology and its individual units and assemblies, in order to timely replace and update.

To date, it can be noted that the economic effect of investments in the purchase of Chinese-made mining equipment has been obtained, due to which we now have the opportunity to minimize the potential risks of downtime from various equipment breakdowns, as well as to ensure uninterrupted and correct operation of machines in technology and the implementation of production programs and expectations of our Customers.

In 2023, a modern spacious hangar for the repair and storage of self-propelled equipment was commissioned. The hangar is heated, which allows it to be used all year round, meets all technical requirements and is equipped with units for operational repairs. Next to it, in September of this year, the frame of the second hangar of a similar purpose has already been erected, which will allow us to promptly carry out the necessary maintenance of precinct vehicles.

The application for the following subspecies of the licensed activity was received:

• Stripping and development of deposits of solid minerals by open pit and underground methods;
• Extraction of solid minerals (except for commonly occurring minerals).

PDF Operation of mining and chemical production facilities

From April to September 2021, a modern two-storey office on the territory of the production base was completely reconstructed and commissioned on September 29, 2021. Companies. The building is autonomously heated, supplied with water and meets all technical requirements. On the ground floor there is a technical unit and a boiler room, there is a utility room, a bathroom and a kitchen for staff. On the second floor, six comfortable workplaces are organized in the style of «Open Space»

The repair included: complete replacement of the main load-bearing steel structures, replacement of all mechanisms and drives, as well as the rotor of the car dumper.

Coordinated and properly organized preparatory and ongoing work made it possible to deliver the facility 7 days earlier than the planned delivery date, which amounted to 36 days.

The work of specialists "Kazinteretnos" almost always takes place in difficult mining and geological conditions. Competent organization of workplace safety, training of personnel, providing them with high-quality personal protective equipment in sufficient quantity comes to the fore.

- The Company has its own occupational safety programs, and our employees also follow all the rules and instructions that are applied at partner enterprises, - says Mikhail Marilov, an occupational safety engineer at the Ridder Site of Kazinteretnos LLP. - Our employees receive security training at least once a year as part of their professional duties. The notification system about the deadline for the recertification of employees in Kazzinc LLP is fully automated. During employment, the data of each employee is entered into the Integrated Work Safety System "ISOBR". The program will notify you in advance when and to what extent a particular employee needs to update their knowledge. Compliance with safety and labor protection in the workplace is monitored on an ongoing basis by both the inspectors of Kazzinc LLP and the engineering staff of Kazinteretnos. Comments (if they are identified) are promptly brought to the attention of the Contractor and are also promptly worked out by him. It turns out that the control is double.

Without proper instruction and study of the necessary hazard protocols, no person, whether a worker or an employee of a third-party contractor, will get to the work site of Kazinteretnos.

Compliance with safety has become an integral part of the work. This area in the "Kazinteretnos" is developing, improving, the most advanced methods of organizing safe work are being introduced. And this is bearing fruit. Reducing injuries and increasing the responsible attitude of employees to their safety and the safety of others – on the face.

- The psychology of our people is changing, - says Dmitry Melkobrodov, Deputy Director for the production of the Artemyevskaya site of Kazinteretnos LLP. - Everyone watches not only themselves, but also their colleagues. No one will pass by if they see that someone is not working safely nearby. We welcome and encourage such facts. Security begins already with a walk-through, with a secondment. No one will be surprised, for example, by the SLAM system of individual risk assessment at workplaces. Compliance with safety and health regulations has become an integral part of the work.

Step-by-step control is in place to minimize risks at the production sites of "Kazinteretnos". It is built in such a way that a dangerous moment will necessarily be identified, if not by an employee, then by his master, or by the deputy head of the site, and so on, according to the hierarchy.

- We also consider an important point to increase the loyalty of our employees," notes Yakov Helvig. We are well aware that this is directly related to security. High wages, organization of comfortable working conditions, observance of the rights of employees - all this makes work in the company honorable. And an employee who values his workplace is much more responsible for all the requirements imposed by the employer. Including safety regulations.

Labor protection today has reached the same high level as the quality of work performed. The "Kazinteretnos" realized this a long time ago. And that is why the leading mining companies of Kazakhstan are among our partners.
