Study on the laws of the mine pressure appearance of the large tilt angle compound mining in Ⅱ661 Work Face of Liuqiao Coal mine
Abstract：Based on parameters of the hydraulic support, such as setting load and working resistance which from the large tilt angle compound mining in II661 Work Face of Liuqiao Coal mine,the paper analyzed the laws of the mine pressure appearance of the downward mining period and the upward mining period. The conclusion of the study can offer a reference to the similar geologic mine of Liuqiao Coal mine around the areaa.
