Taking a general view of the paper, major innovative ideas and returns are as follows: The main innovative ideas are as follows: 1. The paper put forward the new idea that combine water-saving drilling with rotary percussion drilling creatively according to the present situation of water resource lack seriously and the background of implementation of state geological survey strategy. 2. The working principle of new designed system of water-saving hydraulic percussion device completely different from traditional hydraulic percussion device, the system can carry out rotary percussion drilling on the condition that no surface water be consumed, and achieve the purposes that saving surface water, cutting cost and improving drilling efficiency. 3. The design conception of steel ball percussion device is very novel, the percussion device is durable, with a simple structure, at the same time drilling efficiency would be improved highly and drilling cost would be reduced greatly when drill with the steel ball percussion device.
