U.S. EPA seeks advice on emergency use of a new pesticide

Drying equipment

The US Environmental Protection Agency (EPA) received a special exemption request from the agricultural sector in Montana, hoping to urgently ban the use of Bacillus sp. J for the prevention and control of 2,675 acres of potato virus Y (PVY)-infected potato crops. This pesticide has not yet been registered with the EPA. The EPA is now open for consultation until June 11, 2012.

The hydraulic support system used in mines is used to support equipment during the mining process of coal mines or other underground mines.
It mainly consists of hydraulic supports, hydraulic stations, control systems, and sensors.
Hydraulic support is the core component of the hydraulic support system used in mines, which uses hydraulic cylinders as the support force source,
Capable of supporting huge rock weights in underground mines. The hydraulic station provides a hydraulic oil source,
Hydraulic oil is transported to the hydraulic support through pipelines to achieve support function.
The control system is an important component of the hydraulic support system used in mines, which controls and monitors the hydraulic support through sensors and controllers. Sensors can monitor the status of the bracket in real-time, including support force
The controller controls the hydraulic support based on the feedback data from sensors, such as inclination and displacement, to ensure its stability and safety in the mine.
The hydraulic support system used in mines has advantages such as high support force, good stability, and safety and reliability,
Widely used in underground mining industries such as coal mines, metal mines, and non-metallic mines. With the continuous progress of technology and the continuous expansion of applications, hydraulic support systems for mines will continue to play an important role,
Provide strong support for the safe and efficient development of the underground mining industry.
