摘要
随着综采技术的发展,综采工作面端头顶板事故虽逐年减少,但事故率仍居高不下,改善综采工作面端头的支护状况,实现综采工作面高产高效和提高安全程度显得尤为重要,所以端头既是项板维护的重点,又是顶板管理的难点。
With the development of coal mine fully mechanized, roof of top coal caving working face accident is reduced every year. Accident rate is still increasing. Improving sustain situation of top - coal caving working face. Achieve fully mechanized high yield. Concentrated and improve safe degree seem move importance. So it is importance of protect roof, it is difficult to protect roof. Coal mining machine working face lubricate and maintenance is comected with the main problem of service life of a machine work. Mine working face machinery work directly relation mine of produces. Take care of coal - mining working face and kinds of machinery equipment of lubricate and maintenance is an inignored question.
