PVC sealing pipe applications: Dust and gas during coal mining pose significant hazards to miner health and national property. Using coal seam water injection pumps to inject water into the coal body before mining can fundamentally prevent the hazards of coal dust and gas. After injection, the coal body becomes moist, preventing dust from rising and improving working conditions; it can expel gas, ensuring safe production; and it can relax the coal body, enhancing coal mining efficiency. Different specifications of water injection pumps can be selected for water injection into coal seams with varying geological conditions. This type of product is an ideal specialized equipment in the coal seam water injection process.

PVC sealed hole pipes, when used with deep and shallow hole coal seam water injection equipment, offer the following advantages: 1. Suitable for water injection in coal mining faces and heading advancement; 2. Enables hydraulic drilling (hydraulic coal drill); 3. Solves the issue of dust prevention through heading spray; 4. Overcomes the problem of waterless operation during heading advancement; 5. Can be used as temporary support for heading advancement with single hydraulic props, handling side collapses, roof falls, shed support, modification of sheds, and timely support to control roof subsidence, avoiding empty roof operations.
