近年来随着煤炭开采工艺的改革,轻放开采技术在淮北矿区迅速推广,已成为厚煤层开采的主要方法,但是在实际开采过程中,实践认为,制约轻放工作面安全生产的因素很多,比如:顶板管理,瓦斯防治,防灭尘,支架状态,设备完好等。其中顶板管理尤其重要,如何搞好轻放工作面的顶板管理工作,实现安全高产高效,以23113工作面为例加以分析探讨。
In recent years, along with the reform of coal mining technology, the technology of light-weight mining has been rapidly popularized in Huaibei mining area and has become the main method of mining thick coal seam. However, in actual mining process, practice holds that there are many factors restricting safe production of light- For example: roof management, gas prevention and control, anti-dust, stent status, equipment intact. The roof management is particularly important. How to do a good job in the roof management of the working face to achieve safe, high yield and high efficiency, taking 23113 face as an example to analyze and discuss.
