  • Experimental Study on Briquette Coal Sample Mechanics

    Experimental Study on Briquette Coal Sample Mechanics

    Microcracks nucleate and grow in the coal sample, the stress–time curve begins to deviate from a straight line, and the coal sample’s initial damage begins to develop. The coal sample’s internal microcracks start to expand, which is an early signal that the coal sample is damaged.

    Bond Work Index - an overview | ScienceDirect Topics

    The ball mill work index laboratory test is conducted by grinding an ore sample prepared to 100% passing 3.36 mm (6 mesh) to product size in the range of 45-150 m (325-100 mesh), thus determining the ball mill work index (Wi B or BWi). The work index calculations across a narrow size range are conducted using the appropriate laboratory work ...

  • Evolution of Mechanical Properties and Acoustic Emission

    Evolution of Mechanical Properties and Acoustic Emission

    Simulation of raw coal using briquette coal samples with similar mechanical properties and acoustic emission (AE) characteristics is quite instrumental in various analog models. Uniaxial compression with AE monitoring of raw coal and briquette coal samples with a 7% content of different types of binders was conducted using an RMT-150B electrohydraulic test bench. The compression process could ...
