<a href="https://laohu8.com/S/CSUAY">China Shenhua</a> Energy Granted National Patent for Innovative Coal Seam Roof Staged Fracturing Technology

China Shenhua Energy Company Ltd. has been granted a national invention patent for its Work Pipe Assembly for Staged Fracturing of Coal Seam Roofs. The patented technology introduces a multi-stage pressure threshold pre-setting mechanism, allowing precise configuration of fracturing pressure parameters tailored to various coal seam roof characteristics. This modular design improves operational reliability and construction efficiency while reducing risks such as drill sticking and packer failure. The innovation enables the formation of uniform fracture networks in the rock strata, effectively weakening roof strength, mitigating hazards like cantilevered roofs and excessive lateral abutment pressure, and lowering the risk of gas accumulation. The technology is expected to enhance construction precision and safety, offering a replicable solution for mines facing similar geological challenges.
