2m→9.4m! XCMG EBZ320 efficiently excavates the phosphate mine in Guizhou

In a certain phosphate mine in Guizhou Province, the tunneling machine of XCMG Coal Mine has advanced over 150 meters in the first month, with the highest single-day tunneling reaching 9.4 meters. It has exceeded 8 meters for three consecutive days and is expected to reach 200 meters next month... The performance and construction efficiency of XCMG EBZ320 products have once again received high praise from customers

The mining layer constructed by XCMG roadheaders is located below the local erosion reference plane, with multiple faults diagonally crossing through it and various working conditions interweaving, making the construction quite challenging.

Facing numerous challenges such as underground negative slope excavation, water accumulation at the working face, high rock strength, low support efficiency, and unskilled operators, the XCMG service team and the construction unit delved into the site to discuss solutions one by one, gradually increasing the excavation efficiency from the initial 2 meters per day to a maximum of 9.4 meters per day, and safely and efficiently completed the excavation test.

At present, XCMG's coal mine roadheaders have achieved breakthroughs in many major projects both at home and abroad. In a certain mine in Shaanxi Province, the monthly advance exceeded 200 meters, setting a new record for rock tunnel excavation. In a certain mine in Pingdingshan, 280 meters of hard rock roadways are excavated every month. In a certain mine in Yongcheng, the average monthly advance is about 295 meters, breaking the record of 150 meters per month set by other brands of coal mine tunnel boring machines, and the construction efficiency has nearly doubled.

This tunneling operation has exceeded expectations. Compared with similar products in the industry, it has demonstrated core competitive advantages in terms of performance, footage progress and failure rate.

The XCMG EBZ320 coal mine roadheader, mainly developed for large-scale roadways, hard rock construction and tunnel boring projects, features stability and reliability, high safety, and easy disassembly and assembly. It is also equipped with safety protection functions such as remote control and anti-collision monitoring of the cutting mechanism, which has improved the intelligent control level of the entire machine.

The application of this equipment has reduced safety risks, significantly enhanced tunneling efficiency, shortened tunnel development time, and provided strong support for the realization of the client's production plan deployment. Meanwhile, the mine has also adopted efficient mechanical equipment such as XCMG anchor bolt trolleys, injecting strong impetus into the mine.

The commissioning of XCMG roadheaders will help the project construction reach a new height. High-quality, high-efficiency, high-benefit and sustainable XCMG equipment ensures that every customer is worry-free and meets their super value demands
