摘要：
A face equipment for mechanical extraction in longwall mining, in particular in the underground hard coal mining industry, includes a face conveyor (17) arranged along the mining wall, an extraction device (18) that can be moved along the face conveyor (17), and shield support frames (10) supported on the face conveyor (17) at an angle thereto. In order to determine the height of the face opening, a flexible hose level (21) with a liquid-filled hose (22) placed between the face conveyor (17) and at least one main component of the shield support frame (10) is installed in the area of the face conveyor (17). A pressure sensor (23, 24, 28) is arranged on at least one end of the hose (22). An inclination measuring device (25, 26) is arranged on the face conveyor (17) and on the main component of the shield support frame (10).
