Research on the Prevention and Control of Blast Impact Pressure in Deep Holes and the Mechanism of Coordinated Extraction of Harmful Gases.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Uncontrolled carbon monoxide (CO) release after deep-hole roof pressure-relief blasting remains a safety problem because conventional shallow drainage often fails to match the strata where blast gases are generated and retained. Here, we clarify the permeability-contrast-controlled retention mechanism and propose an integrated blasting-sealing-extraction framework that couples field diagnosis at the A503 working face, dynamic fracture modeling, confined explosion tests, adsorption-diffusion analysis, and industrial validation. The method uses the critical distance between the fracture front and the coal seam to constrain charge length and places extraction boreholes in the roof gas-enrichment zone rather than only in the coal seam. The A503 measurements showed that the sandstone roof permeability (2.1 × 10
