1 · What the graph read from it

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.

2 · The registry

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

A large amount of coal dust is produced in coal mine excavation, which has a serious impact on the working environment and health of underground workers. For this problem, through numerical simulation to understand the temporal and spatial evolution law of coal dust in the excavation tunnel, that is, the coal dust velocity first increases and then decreases along the diffusion direction, and the maximum velocity reaches 8 m/s, and fills the entire tunnel at 50 s. In this regard, the an ultrafine water mist partition multistage dust suppression system was proposed, and numerical simulation studies were carried out on the wind flow distribution and water mist particle transportation law, and the results showed that the air flow velocity in the 0-5 m area was between 6-14 m/s and varied a lot, and the speed of the spray jet in the 10-30 m area decayed faster, and eventually stabilized at 1 m/s. The water mist particles surrounded the cutting head with a speed of 8 m/s in 2 s, and spread to the working face. After 10 s, the water mist particles cover the whole roadway, and the speed is also stabilized at 2 m/s. Through field application and measurement in the I030409 excavation face of Qipanjing Coal Mine, the average reduction efficiency for total dust and respirable dust in the tunnel reached 91.74% and 93.4%, respectively, which effectively controls the problem of dust pollution in the excavation tunnel.
