With the rapid development of mining mechanization, trackless equipment is becoming more and more favored by major mines, and scrapers are more and more widely used in mines as a flexible mining equipment.Therefore, how to train scraping machinists has become an important issue that mining enterprises cannot fail to consider.Scraper manufacturer

The dilemma faced by traditional training

1.Poor normative job operation training

At present, the job training of scraper mechanics in most mines still continues the traditional model of “teacher with apprentice”, but the job training of scraper involves daily equipment inspection, driving operation, and scraping operation. The training content is complicated, the traditional training model is highly subjective, the operation process is poor, the sense of standardization is not strong, and the inheritance of job operations is poor. Outstanding problems, which greatly affect the efficiency of mine job training and production efficiency.

2.Poor realism of job operation training scenes

In underground mines, scrapers are generally used to shovel ore or waste stones on the surface of the operation industry. Their operating environment is generally located in narrow roadways or high-risk quarries. In order to train students and reduce equipment loss, mines generally arrange the shoveling training of scrapers on the surface, but the surface training cannot simulate the complex underground operating environment. After the surface training is completed, students still have to enter the underground roadway for adaptive training to complete normal shoveling operations, which cannot meet the operating requirements of the mine.

3.High equipment loss rate

Scrapers are an important asset of mining enterprises. They are expensive. In traditional teaching, scrapers are often used directly for practical training and teaching after students have completed their theoretical studies. When students are not familiar with the equipment, it is inevitable that they will misoperate, resulting in equipment failure, damage, injury to personnel and other unpredictable consequences, directly or indirectly leading to an increase in training costs.

Solution of virtual training system

In view of the dilemmas of traditional training, Dimai Technology's virtual training team independently developed the first domestic training product used to simulate the operation of mining scrapers-the scraper virtual training system.

The product consists of two parts: a physical control platform and a virtual control system.It is mainly used to quickly train personnel's scraper operation skills and assess their mastery of content in real time.

The system has the following characteristics：

1.Parameterized equipment

A highly accurate three-dimensional model is constructed based on the real shape and structure data of the scraper, and the corresponding bone movements are given to the model according to its working principle.When students control the scraper, it is like controlling real equipment. It can not only be used to train students in the standardized operation, but also for students to master the control of the equipment and achieve good training results.

2.High degree of operating environment

Based on real mine roadway data and on-site photos, through three-dimensional digital modeling software, high-precision roadway internal layout, rock texture, rock mass cracks, support forms, lighting effects, etc., give students a strong visual impact, just like entering a real underground roadway, it can quickly take students into the post working environment.

3.A training model that combines reality and reality

The system controls the buttons of the physical controller to control the equipment in the virtual scene for training and teaching in the virtual-real combination mode of corresponding operations.

The physical controller is made in proportion to the prototype of the mine remote control equipment, and its buttons, operation methods, indicators, etc. are the same as the real mine remote control equipment.

The virtual control system is a highly restored virtual scene of underground operations composed of parameterized equipment and roadways.

The system can be used not only for proficient remote control equipment control, but also to feel the real environment of scraper operation.The system will not cause loss and injury to equipment and personnel while truly restoring the working environment of the post.

4.Real-time data monitoring and recording

The system has two modes of training and assessment, and is equipped with a variety of operating environments. It can record the alarms caused by errors during the operation of the scraper, loading and unloading, etc. in real time.

Students can understand the working status of the equipment through the dynamic panoramic display panel, and after the training and assessment, they can view the recorded data to understand the content of the deduction and the reason for the deduction, so as to better grasp the operation essentials.Teachers can watch the user's entire operation process and view data records in real time through the dynamic panoramic display panel to judge the students' mastery of knowledge.

Application value of virtual training system

1.Low training cost

The procurement cost of the scraper training system is low, the system can be reused, and the operation is stable, the equipment failure rate is low, students can quickly enter the job practice after training, and the training efficiency is high, which can greatly reduce the training time and directly or indirectly reduce the cost of enterprise training.

2.Training content system and specification

The system training content is complete, including the cognition of equipment and environment, the operation essentials such as equipment travel, steering, lifting arm, loading and unloading, troubleshooting, etc., The training process is standardized, and the position inheritance is good. At the same time, different types of mine environments are also set up, which is conducive to trainees to quickly adapt to the operation essentials of equipment in different environments.

3.Enhance the subjective initiative of employees

The authenticity of the system screen is good, the operation is simple, the equipment control method and operation route are unlimited, and the authenticity is good. The system can evaluate the operation effect in real time, and the operator can be evaluated in real time. The operation is challenging and can greatly stimulate the subjective initiative of students.

4.Reduce the incidence of accidents

The system can realize the seamless connection between training and job operations of trainees, and reduce the failure rate and damage rate of equipment during training and job operations. The system sets up a variety of different types of mine environments, allowing students to quickly respond to similar situations in actual operations and minimize losses.
