Application of New High-Energy Expansion Agent in Coal Mine Roadway Excavation
نویسندگان
چکیده
A new energy material, a high-energy expansion agent (HEEA), was proposed for the harsh engineering environment of mine. safety test and field were carried out. The results showed that mechanical sensitivity HEEA extremely low, no combustion explosion occurred in multiple impact friction tests. Meanwhile, only burns open spaces without detonation. Through experiments, can achieve good blasting effect, providing strong support its promotion low-disturbance environmental applications.

High-tech coal mine canary.
High-tech coal mine canary One of coal mining's earliest systems for warning of the presence of methane gas, the canary in the coal mine, though low-tech, was extremely effective and rather easy to read: if the bird died, miners had to get out of the shaft. Today, the search for means to monitor for signs of danger continues. At an annual checkup, one could be given a whole battery of tests, ea...
متن کاملExtension of Excavation Damaged Zone Due to Longwall Working Effect
In advance longwall mining, the safety of mine network, production rate, and consequently, economic conditions of a mine are dependent on the stability conditions of gate roadways. The gate roadway stability is a function of two important factors: 1) characteristics of the excavation damaged zone (EDZ) above the gate roadway and 2) loading effect due to the caving zone (CZ) above the longwall w...
متن کاملDeformation mechanisms in a coal mine roadway in extremely swelling soft rock
The problem of roadway support in swelling soft rock was one of the challenging problems during mining. For most geological conditions, combinations of two or more supporting approaches could meet the requirements of most roadways; however, in extremely swelling soft rock, combined approaches even could not control large deformations. The purpose of this work was to probe the roadway deformatio...

Taking the roadway in seam in Danhou Coal Mine, as the engineering background, according to the spatial relationship of the roadway, the impermeable layer, the fault and the loading conditions, the fault activation mechanical model under the roadway excavation disturbance was built, and the fault activ...
متن کاملCanaries in the coal mine.
Up until 30 years ago, coalminers relied on canaries as warning systems against harmful gases and pollutants underground. The miners listened for birdsong and if the birds fell silent, then they knew there was danger to their health and to take action. Today we have much more sophisticated information and reporting on the quality of air. We know precisely the levels and composition of pollutant...
