An optimizing microseismic method for rock burst early warning based on mining production process
A classification early warning method of rock burst based on hourly microseismic data is proposed, which can be combined with the on‐site production process to provide more timely warning. Abstract Microseismic (MS) events have been reported in nearly every coal mining country, which could well lead to rock burst in underground coal mines.

CRUDE COAL TAR IN DERMATOLOGY [PDF]
Some years ago, Brocq published a note on the use of crude coal tar in cutaneous diseases. He recommended the application of the substance to weeping surfaces in 100 per cent, strength, and he wrote enthusiastically of its beneficial effects. This note reached America, and at the Massachusetts General Hospital we seized on the idea at once and from ...
