The study discusses the issue of introducing drilling fluid (bentonite) into the environment during the construction of linear underground investments, considering the example of the construction of the high-pressure gas pipeline, Czeszów—Kiełczów DN1000, which involved the use of the Horizontal Directional Drilling (HDD) method. The analyses concern the drilling stage as a low-waste technology, indicating the use and management of bentonite drilling fluid in a closed circulation cycle in the area of Pęciszów, poviat Trzebnica (Poland). The loss of drilling fluid in valuable natural areas during the construction stage of the gas pipeline has been analyzed. Drilling fluid is an element of the horizontal directional drilling technology (HDD). The analyzed area included a section of the route of the strategic gas pipeline, realized in June–July 2017 in an area of lowland ash and alder forest 91E0-3, a probable breeding site of the Bluethroat for a detailed description and common frog. The loss of the drilling fluid used in the drilling phase has been determined, depending on the type of soil and the related fraction as well as the possibility of treating the drilling fluid used to construct the drilling.

Drilling System

Measurement while drilling (MWD) is the key for underground directional drilling in coalmine. In this paper, an uphole monitor for MWD is developed to process and display downhole measure data. Firstly, an explosion-proof computer is developed, which can be used in explosive gas atmosphere. The flameproof enclosure and intrinsic safe type of protection have been employed to meet the needs of explosion-proof and communication with measure unit. A Windows-based software is subsequently developed to show the measure result and generate the in-seam drilling trajectory. The uphole monitor has been integrated into directional drilling system and demonstrated by the application in China’s coalmines.

In the light of more and more urgent hidden fire abnormal detection problem in complex conditions of mine, a method which is used directional drilling technology is put forward. The method can avoid the obstacles in mine, and complete the fire abnormal detection. This paper based on analyzing the trajectory control of directional drilling, measurement while drilling and the characteristic of open branch process, the project of the directional drilling is formulated combination with a complex condition mine, and the detection of fire abnormal is implemented. This method can provide technical support for fire prevention, which also can provide a new way for fire anomaly detection in the similar mine.
