Optimization of Nitrogen Injection Parameters for a Partial W‑Type Ventilation Goaf at Duanwang Mine.
Article in ACS omega, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
To optimize nitrogen injection for preventing coal spontaneous combustion in the goaf, closed oxygen consumption tests and field data calibrated the oxygen criterion for the suffocation zone. A numerical model of the 150405 panel goaf with partial "W" ventilation was established to analyze gas drainage and nitrogen injection effects. Increasing the gas drainage volume narrowed the oxidation zone on the conveyor side but expanded it on the track side. Oxidation zone width first decreased and then slightly increased with injection distance and decayed exponentially with higher injection rates. The optimal injection location was identified 40 m from the face on the conveyor side, with a rate of 145.5 m
