Sustainable application of waste gangue mortar in coal mine tunnel support.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
With the increase in coal mining depths, soft and fractured roadway surrounding rocks require grouting and a sprayed protective layer for maintenance. Simultaneously, extensive accumulation of coal gangue causes diverse environmental issues. To enhance on-site coal gangue utilization, this study replaced river sand and cement with coal gangue to develop a novel cement-based mortar for supporting coal mine roadways. The study examined how apparent density, compressive strength, flexural strength, and fiber reinforcement affect performance, while investigating the hydration reaction mechanism. The results show that compared with ordinary mortar, the apparent density and compressive strength of coal gangue-basalt fiber cementitious mortar are reduced, but its flexural strength is improved. Furthermore, a constitutive model for coal gangue-basalt fiber cement-based mortar under compression was formulated. The model comprehensively assessed the compressive strength of specimens and determined correlation coefficients for the rising and falling sections of the stress-strain curve. Micro-aggregates enhance the internal skeleton density in coal gangue-basalt fiber cement-based mortar.
