Aiming at the challenges of low coalbed methane (CBM) extraction efficiency caused by significant permeabil-ity differences in soft-hard interbedded coal seams and poor adaptability of conventional fracturing technolo-gies in China, this study focuses on the No. 3 soft-hard interbedded coal seam in the Jincheng mining area. A "geology-engineering integration" development concept is proposed, and an innovative staged fracturing tech-nology for horizontal wells with uncemented casing outside the coal seam is developed. By adopting a tub-ing-annulus co-injection fracturing process (injection rate: 8.0–9.0 m3/min, proppant concentration: 6–8 m3/m), combined with self-developed expandable packers (pressure resistance: 70 MPa), sand-control hydraulic an-chors (tensile strength >200 kN), and high-displacement hydraulic jetting-fracturing integrated tools, a "perfo-ration-fracturing" collaborative mode is established to achieve balanced staged stimulation of soft and hard coal layers. Field tests demonstrate that the single-well daily gas production exceeds 5,000 m3, the gas contri-bution rate of soft coal seams increases to 35%, and the gas content reduction reaches 24.2% after two years of extraction. Additionally, the construction cost is reduced by 100,000 yuan per stage, with a 30% improvement in efficiency. This technology effectively resolves issues such as wellbore instability and coal fines blockage, significantly enhances pressure relief volume and extraction efficiency, and provides technical support for coal mine gas hazard prevention, large-scale CBM development, and green mine construction under the “du-al-carbon” goal.
